1. Link to proposed Open Source License
http://www.technicalpursuit.com/RPL.1.1

2. Justification for a New license
The Reciprocal Public License (RPL) is a license
derived largely from the Apple Public Source License
or APSL version 1.2 and the GNU General Public License
version 2. The LGPL and MPL were also referenced, as
was the Jabber Open Source License. Our main goal in
creating the RPL was to create a license similar in
intent to the GPL with respect to being "viral", but
which did not include a "privacy clause" such as that
found in the GPL. In particular, we wanted to ensure
that consumers of RPL code were required to release
their source code under the RPL subsequent to any
deployment, internal or otherwise. We further wanted
to create terminology surrounding the question of what
code was covered that did not rely on terms such as
"linking" etc. which are difficult to define in a
world dominated by interpreted languages and virtual
machines. The RPL's use of the term "Required
Components" addresses this issue while attempting to
remain open to the integration of RPL-based code with
code from other licenses. One additional goal was to
create a license that could be used by other parties
in licensing their code, therefore we've attempted to
limit references to a specific company and provided
for the construction of derivative licenses whose only
modification is to the Notice required in each source
code file, as well as other license derivatives so
long as they are renamed to avoid confusion. 

3. How software distributed under our license can be
used in conjunction with software distributed under
other open source licenses.

We feel the RPL is compatible for use with other open
source licenses. First, the RPL makes no claims on
code which is not authored by the licensee. For code
which is authored by the licensee there are a few
scenarios. If the new code wouldn't be covered by
another license the RPL applies and the new code is
inherently governed by the RPL. When code authored by
the licensee is a derivative work of code licensed
under a different license, the RPL requires that the
new code be dual-licensed such that both licenses may
be honored while ensuring that a pure-RPL version
remains available to all parties(this does have the
effect of requiring disclosure in situations where the
GPL would not-derivative code used internally in large
companies or government institutions must be disclosed
for example). When, for some reason, a conflict in
license terms would still exist the RPL specifies that
the licensee should contact the Licensor for
permission to resolve the conflicting terms in a
fashion which remains consistent with the intent of
the RPL. See Section 6.6 for specific wording here.

RECIPROCAL PUBLIC LICENSE

Version 1.1, November 1, 2002

Copyright (C) 2001-2002
Technical Pursuit Inc.,
All Rights Reserved.

PREAMBLE

This Preamble is intended to describe, in plain English, the nature,
intent, and scope of this License. However, this Preamble is not a part
of this License. The legal effect of this License is dependent only upon
the terms of the License and not this Preamble.

This License is based on the concept of reciprocity. In exchange for
being granted certain rights under the terms of this License to
Licensor's Software, whose Source Code You have access to, You are
required to reciprocate by providing equal access and rights to all
third parties to the Source Code of any Modifications, Derivitive Works,
and Required Components for execution of same (collectively defined as
Extensions) that You Deploy by Deploying Your Extensions under the terms
of this License. In this fashion the available Source Code related to
the original Licensed Software is enlarged for the benefit of everyone.

Under the terms of this License You may:

a. Distribute the Licensed Software exactly as You received it under the
   terms of this License either alone or as a component of an aggregate
   software distribution containing programs from several different
   sources without payment of a royalty or other fee.

b. Use the Licensed Software for any purpose consistent with the rights
   granted by this License, but the Licensor is not providing You any
   warranty whatsoever, nor is the Licensor accepting any liability in
   the event that the Licensed Software doesn't work properly or causes
   You any injury or damages.

c. Create Extensions to the Licensed Software consistent with the rights
   granted by this License, provided that You make the Source Code to
   any Extensions You Deploy available to all third parties under the
   terms of this License, document Your Modifications clearly, and title
   all Extensions distinctly from the Licensed Software.

d. Charge a fee for warranty or support, or for accepting indemnity or
   liability obligations for Your customers.

Under the terms of this License You may not:

a. Charge for the Source Code to the Licensed Software, or Your
   Extensions, other than a nominal fee not to exceed Your cost for
   reproduction and distribution where such reproduction and
   distribution involve physical media.

b. Modify or delete any pre-existing copyright notices, change notices,
   or License text in the Licensed Software.

c. Assert any patent claims against the Licensor or Contributors, or
   which would in any way restrict the ability of any third party to use
   the Licensed Software or portions thereof in any form under the terms
   of this License, or Your rights to the Licensed Software under this
   License automatically terminate.

d. Represent either expressly or by implication, apppearance, or
   otherwise that You represent Licensor or Contributors in any capacity
   or that You have any form of legal association by virtue of this
   License.

Under the terms of this License You must:

a. Document any Modifications You make to the Licensed Software
   including the nature of the change, the authors of the change, and
   the date of the change. This documentation must appear both in the
   Source Code and in a text file titled "CHANGES" distributed with the
   Licensed Software and Your Extensions.

b. Make the Source Code for any Extensions You Deploy available in a
   timely fashion via an Electronic Distribution Mechanism such as FTP
   or HTTP download.

c. Notify the Licensor of the availability of Source Code to Your
   Extensions in a timely fashion and include in such notice a brief
   description of the Extensions, the distinctive title used, and
   instructions on how to acquire the Source Code and future updates.

d. Grant Licensor and all third parties a world-wide, non-exclusive,
   royalty-free license under any intellectual property rights owned or
   controlled by You to use, reproduce, display, perform, modify,
   sublicense, and distribute Your Extensions, in any form, under the
   terms of this License.

since you have not signed it, however nothing else grants you permission
to use, copy, distribute, modify, or create derivatives of either the
Software or any Extensions created by a Contributor. These actions are
prohibited by law if you do not accept this License. Therefore, by
performing any of these actions You indicate Your acceptance of this
License and Your agreement to be bound by all its terms and conditions.

deemed to grant any rights to trademarks, copyrights, patents, trade
secrets or any other intellectual property of Licensor or any
Contributor except as expressly stated herein. Except as expressly
stated in Sections 3 and 4, no other patent rights, express or implied,
are granted herein. Your Extensions may require additional patent
licenses from Licensor or Contributors which each may grant in its sole
discretion. No right is granted to the trademarks of Licensor or any
Contributor even if such marks are included in the Licensed Software.
Nothing in this License shall be interpreted to prohibit Licensor from
licensing under different terms from this License any code that Licensor
otherwise would have a right to license.

5.1 You expressly acknowledge and agree that although Licensor and each
Contributor grants the licenses to their respective portions of the
Licensed Software set forth herein, no assurances are provided by
Licensor or any Contributor that the Licensed Software does not infringe
the patent or other intellectual property rights of any other entity.
Licensor and each Contributor disclaim any liability to You for claims
brought by any other entity based on infringement of intellectual
property rights or otherwise. As a condition to exercising the rights
and licenses granted hereunder, You hereby assume sole responsibility to
secure any other intellectual property rights needed, if any. For
example, if a third party patent license is required to allow You to
distribute the Licensed Software, it is Your responsibility to acquire
that license before distributing the Licensed Software.

6.0 Your Obligations And Grants. In consideration of, and as an express
condition to, the licenses granted to You under this License You hereby
agree that any Modifications, Derivative Works, or Required Components
(collectively Extensions) that You create or to which You contribute are
governed by the terms of this License including, without limitation,
Section 4. Any Extensions that You create or to which You contribute
must be Deployed under the terms of this License or a future version
of this License released under Section 7. You hereby grant to Licensor
and all third parties a world-wide, non-exclusive, royalty-free license
under those intellectual property rights You own or control to use,
reproduce, display, perform, modify, create derivatives, sublicense, and
distribute Your Extensions, in any form. Any Extensions You make and
Deploy must have a distinct title so as to readily tell any subsequent
user or Contributor that the Extensions are by You. You must include a
copy of this License with every copy of the Extensions You distribute.
You agree not to offer or impose any terms on any Source Code or
executable version of the Licensed Software, or its Extensions that
alter or restrict the applicable version of this License or the
recipients' rights hereunder.

6.1 Availability of Source Code. You must make available, under the
terms of this License, the Source Code of the Licensed Software and any
Extensions that You Deploy, either on the same media as You distribute
any executable or other form of the Licensed Software, or via an
Electronic Distribution Mechanism. The Source Code for any version of
Licensed Software, or its Extensions that You Deploy must be made
available at the time of Deployment and must remain available for as
long as You Deploy the Extensions or at least twelve (12) months after
the date You Deploy, whichever is longer. You are responsible for
ensuring that the Source Code version remains available even if the
Electronic Distribution Mechanism is maintained by a third party. You
may not charge a fee for the Source Code distributed under this Section
in excess of Your actual cost of duplication and distribution where such
duplication and distribution involve physical media.

6.2 Description of Modifications. You must cause any Modifications that
You create or to which You contribute, to update the file titled
"CHANGES" distributed with Licensed Software documenting the additions,
changes or deletions You made, the authors of such Modifications, and
the dates of any such additions, changes or deletions. You must also
cause a cross-reference to appear in the Source Code at the location of
each change. You must include a prominent statement that the
Modifications are derived, directly or indirectly, from the Licensed
Software and include the names of the Licensor and any Contributor to
the Licensed Software in (i) the Source Code and (ii) in any notice
displayed by the Licensed Software You distribute or in related
documentation in which You describe the origin or ownership of the
Licensed Software. You may not modify or delete any pre-existing
copyright notices, change notices or License text in the Licensed
Software.

6.3Intellectual Property Matters.

a. Third Party Claims. If You have knowledge that a license to a third
   party's intellectual property right is required to exercise the
   rights granted by this License, You must include a text file with the
   Source Code distribution titled "LEGAL" that describes the claim and
   the party making the claim in sufficient detail that a recipient will
   know whom to contact. If You obtain such knowledge after You make any
   Extensions available as described in Section 6.1, You shall promptly
   modify the LEGAL file in all copies You make available thereafter and
   shall take other steps (such as notifying appropriate mailing lists
   or newsgroups) reasonably calculated to inform those who received the
   Licensed Software from You that new knowledge has been obtained.

b. Contributor APIs. If Your Extensions include an application
   programming interface ("API") and You have knowledge of patent
   licenses that are reasonably necessary to implement that API, You
   must also include this information in the LEGAL file.

c. Representations. You represent that, except as disclosed pursuant to
   6.3(a) above, You believe that any Extensions You distribute are Your
   original creations and that You have sufficient rights to grant the
   rights conveyed by this License.

6.4 Required Notices.

a. License Text. You must duplicate this License in any documentation
   You provide along with the Source Code of any Extensions You create
   or to which You contribute, wherever You describe recipients' rights
   relating to Licensed Software. You must duplicate the notice
   contained in EXHIBIT A (the "Notice") in each file of the Source Code
   of any copy You distribute of the Licensed Software and Your
   Extensions. If You create an Extension, You may add Your name as a
   Contributor to the text file titled "CONTRIB" distributed with the
   Licensed Software along with a description of the contribution. If it
   is not possible to put the Notice in a particular Source Code file
   due to its structure, then You must include such Notice in a location
   (such as a relevant directory file) where a user would be likely to
   look for such a notice.

b. Source Code Availability. You must notify Licensor within one (1)
   month of the date You initially Deploy of the availability of Source
   Code to Your Extensions and include in such notification the name
   under which you Deployed Your Extensions, a description of the
   Extensions, and instructions on how to acquire the Source Code,
   including instructions on how to acquire updates over time.  Should
   such instructions change you must provide Licensor with revised
   instructions within one (1) month of the date of change. Should you
   be unable to notify Licensor directly, you must provide notification
   by posting to appropriate news groups, mailing lists, or web sites
   where a search engine would reasonably be expected to index them.

6.5 Additional Terms. You may choose to offer, and charge a fee for,
warranty, support, indemnity or liability obligations to one or more
recipients of Licensed Software.  However, You may do so only on Your
own behalf, and not on behalf of the Licensor or any Contributor. You
must make it clear that any such warranty, support, indemnity or
liability obligation is offered by You alone, and You hereby agree to
indemnify the Licensor and every Contributor for any liability plus
attorney fees, costs, and related expenses due to any such action or
claim incurred by the Licensor or such Contributor as a result of
warranty, support, indemnity or liability terms You offer.

6.6 Conflicts With Other Licenses. Where any portion of Your Extensions,
by virtue of being Derivative Works of another product or similar
circumstance, fall under the terms of another license, the terms of that
license should be honored however You must also make Your Extensions
available under this License. If the terms of this License continue to
conflict with the terms of the other license you may write the Licensor
for permission to resolve the conflict in a fashion that remains
consistent with the intent of this License. Such permission will be
granted at the sole discretion of the Licensor.

7.0Versions of This License. Licensor may publish from time to time
revised and/or new versions of the License. Once Licensed Software has
been published under a particular version of the License, You may always
continue to use it under the terms of that version. You may also choose
to use such Licensed Software under the terms of any subsequent version
of the License published by Licensor. No one other than Licensor has the
right to modify the terms applicable to Licensed Software created under
this License.

7.1 If You create or use a modified version of this License, which You
may do only in order to apply it to software that is not already
Licensed Software under this License, You must rename Your license so
that it is not confusingly similar to this License, and must make it
clear that Your license contains terms that differ from this License. In
so naming Your license, You may not use any trademark of Licensor or of
any Contributor. Should Your modifications to this License be limited to
alteration of EXHIBIT A purely for purposes of adjusting the Notice You
require of licensees, You may continue to refer to Your License as the
Reciprocal Public License or simply the RPL.

8.0 Disclaimer of Warranty. LICENSED SOFTWARE IS PROVIDED UNDER THIS
LICENSE ON AN "AS IS" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER
EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE
LICENSED SOFTWARE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR

THE TERMS OF THIS LICENSOR WILL NOT SUPPORT THIS SOFTWARE AND IS UNDER
NO OBLIGATION TO ISSUE UPDATES TO THIS SOFTWARE. LICENSOR HAS NO
KNOWLEDGE OF ERRANT CODE OR VIRUS IN THIS SOFTWARE, BUT DOES NOT WARRANT
THAT THE SOFTWARE IS FREE FROM SUCH ERRORS OR VIRUSES.  THIS DISCLAIMER
OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
LICENSED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

9.0Limitation of Liability. UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL
THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE,
SHALL THE LICENSOR, ANY CONTRIBUTOR, OR ANY DISTRIBUTOR OF LICENSED
SOFTWARE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY
PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES
OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF
GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL

RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION
AND LIMITATION MAY NOT APPLY TO YOU.

10.0 High Risk Activities. THE LICENSED SOFTWARE IS NOT FAULT-TOLERANT
AND IS NOT DESIGNED, MANUFACTURED, OR INTENDED FOR USE OR DISTRIBUTION
AS ON-LINE CONTROL EQUIPMENT IN HAZARDOUS ENVIRONMENTS REQUIRING
FAIL-SAFE PERFORMANCE, SUCH AS IN THE OPERATION OF NUCLEAR FACILITIES,
AIRCRAFT NAVIGATION OR COMMUNICATIONS SYSTEMS, AIR TRAFFIC CONTROL,

OF THE LICENSED SOFTWARE COULD LEAD DIRECTLY TO DEATH, PERSONAL INJURY,
OR SEVERE PHYSICAL OR ENVIRONMENTAL DAMAGE ("HIGH RISK ACTIVITIES").
LICENSOR AND CONTRIBUTORS SPECIFICALLY DISCLAIM ANY EXPRESS OR IMPLIED
WARRANTY OF FITNESS FOR HIGH RISK ACTIVITIES.

11.0 Responsibility for Claims. As between Licensor and Contributors,
each party is responsible for claims and damages arising, directly or
indirectly, out of its utilization of rights under this License which
specifically disclaims warranties and limits any liability of the
Licensor. This paragraph is to be used in conjunction with and
controlled by the Disclaimer Of Warranties of Section 8, the Limitation
Of Damages in Section 9, and the disclaimer against use for High Risk
Activities in Section 10. The Licensor has thereby disclaimed all
warranties and limited any damages that it is or may be liable for. You
agree to work with Licensor and Contributors to distribute such
responsibility on an equitable basis consistent with the terms of this
License including Sections 8, 9, and 10.  Nothing herein is intended or
shall be deemed to constitute any admission of liability.

12.0 Termination. This License and all rights granted hereunder will
terminate immediately in the event of the circumstances described in
Section 13.6 or if applicable law prohibits or restricts You from
fully and or specifically complying with Sections 3, 4 and/or 6, or
prevents the enforceability of any of those Sections, and You must
immediately discontinue any use of Licensed Software.

12.1 Automatic Termination Upon Breach. This License and the rights
granted hereunder will terminate automatically if You fail to comply
with the terms herein and fail to cure such breach within thirty (30)
days of becoming aware of the breach. All sublicenses to the Licensed
Software that are properly granted shall survive any termination of this
License. Provisions that, by their nature, must remain in effect beyond
the termination of this License, shall survive. 

12.2 Termination Upon Assertion of Patent Infringement. If You initiate
litigation by asserting a patent infringement claim (excluding
declaratory judgment actions) against Licensor or a Contributor
(Licensor or Contributor against whom You file such an action is
referred to herein as "Respondent") alleging that Licensed Software
directly or indirectly infringes any patent, then any and all rights
granted by such Respondent to You under Sections 3 or 4 of this License
shall terminate prospectively upon sixty (60) days notice from
Respondent (the "Notice Period") unless within that Notice Period You
either agree in writing (i) to pay Respondent a mutually agreeable
reasonably royalty for Your past or future use of Licensed Software made
by such Respondent, or (ii) withdraw Your litigation claim with respect
to Licensed Software against such Respondent. If within said Notice
Period a reasonable royalty and payment arrangement are not mutually
agreed upon in writing by the parties or the litigation claim is not
withdrawn, the rights granted by Licensor to You under Sections 3 and 4
automatically terminate at the expiration of said Notice Period.

12.3 Reasonable Value of This License. If You assert a patent
infringement claim against Respondent alleging that Licensed Software
directly or indirectly infringes any patent where such claim is resolved
(such as by license or settlement) prior to the initiation of patent
infringement litigation, then the reasonable value of the licenses
granted by said Respondent under Sections 3 and 4 shall be taken into
account in determining the amount or value of any payment or license.

12.4 No Retroactive Effect of Termination. In the event of termination
under this Section all end user license agreements (excluding licenses
to distributors and resellers) that have been validly granted by You or
any distributor hereunder prior to termination shall survive
termination.

13.0 Miscellaneous.

13.1 U.S. Government End Users. The Licensed Software is a "commercial
item," as that term is defined in 48 C.F.R. 2.101 (Oct. 1995),
consisting of "commercial computer software" and "commercial computer
software documentation," as such terms are used in 48 C.F.R. 12.212
(Sept. 1995). Consistent with 48 C.F.R.  12.212 and 48 C.F.R. 227.7202-1
through 227.7202-4 (June 1995), all U.S.  Government End Users acquire
Licensed Software with only those rights set forth herein.

13.2 Relationship of Parties. This License will not be construed as
creating an agency, partnership, joint venture, or any other form of
legal association between or among You, Licensor, or any Contributor,
and You will not represent to the contrary, whether expressely, by
implication, appearance, or otherwise.

13.3 Independent Development. Nothing in this License will impair
Licensor's right to acquire, license, develop, subcontract, market, or
distribute technology or products that perform the same or similar
functions as, or otherwise compete with, Extensions that You may
develop, produce, market, or distribute.

13.4 Consent To Breach Not Waiver. Failure by Licensor or Contributor to
enforce any provision of this License will not be deemed a waiver of
future enforcement of that or any other provision.

13.5 Severability. This License represents the complete agreement
concerning the subject matter hereof. If any provision of this License
is held to be unenforceable, such provision shall be reformed only to
the extent necessary to make it enforceable. 

13.6 Inability to Comply Due to Statute or Regulation. If it is
impossible for You to comply with any of the terms of this License with
respect to some or all of the Licensed Software due to statute, judicial
order, or regulation, then You cannot use, modify, or distribute the
software.

13.7 Export Restrictions. You may be restricted with respect to
downloading or otherwise acquiring, exporting, or reexporting the
Licensed Software or any underlying information or technology by United
States and other applicable laws and regulations. By downloading or by
otherwise obtaining the Licensed Software, You are agreeing to be
responsible for compliance with all applicable laws and regulations.

13.8 Arbitration, Jurisdiction & Venue. This License shall be governed
by Colorado law provisions (except to the extent applicable law, if any,
provides otherwise), excluding its conflict-of-law provisions. You
expressly agree that any dispute relating to this License shall be
submitted to binding arbitration under the rules then prevailing of the
American Arbitration Assocation. You further agree that Adams County,
Colorado USA is proper venue and grant such arbitration proceeding
jurisdiction as may be appropriate for purposes of resolving any dispute
under this License. Judgement upon any award made in arbitration may be
entered and enforced in any court of competent jurisdiction. The
arbitrator shall award attorney's fees and costs of arbitration to the
prevailing party. Should either party find it necessary to enforce its
