For now I'll limit myself to comparing the summary
of problems that you wrote August 20 2000 , with
the current license [2,3].
There may of course be other issues not covered in
your summary, though it was in my judgment a good
summary of the situation as the license was at that
> 1) Lucent reserves the right to demand source
> code for your private undistributed modifications;
The current (as at Nov 03 2002) license says:
"Modifications which You create ... must be made
available under the terms of this Agreement in at
least the same form as the Source Code version of
Original Software furnished hereunder."
They don't explicitly exclude private changes.
But I doubt they really care, so I think this
could be fixed easily.
"You agree to provide the Original Contributor,
at its request, with a copy of the complete Source
Code version, Object Code version and related
documentation for Modifications created or
contributed to by You if distributed in any
They don't define "distribute" or any variant of
the word. But again, although with less certainty,
I suspect they would not mind about private
distribution (within a single entity) and could
fix the wording.
> 2) commercial redistribution can only be for a
> "reasonable" price, an undefined term that might
> lead to trouble later;
"Distribution ... may ... include a reasonable
charge for the cost of any media. You may also,
at Your option, charge for any other software,
product or service that includes or incorporates
the Original Software as a part thereof."
I believe the last sentence was added after your
summary. Afaict, it mostly fixes the problem.
> 3) the license conditions are reimposed on your
> distributees, which suggests that you must have
> an explicit contract with them (I think RMS is
> overdoing it here);
I'm not sure what this is about so I won't try
to review this.
> 4) the retaliation clause causes you to lose all
> rights if you sue Lucent on any IP matter whatever,
> even if it has nothing to do with Plan 9;
"The licenses and rights granted under this
Agreement shall terminate automatically if ...
(ii) You initiate or participate in any
intellectual property action against Original
So, this problem remains.
Note that, from
[Eric] Raymond favors a "Chinese finger
trap" provision for future licenses: under
its terms, if you initiate patent legal
action against the copyright holder, you
lose your license rights.
Ironic, huh? (Although what he actually said
or meant may have been less extreme than the
above seems to imply.)
> 5) the license imposes the U.S. export regulations
> on you if you export the software, even if they
> would not otherwise apply as a matter of law.
"You acknowledge that the Licensed Software
hereunder is "unrestricted encryption source
code" as the term is defined under the United
States Export Administration Regulations and
is subject to export control under such laws
and regulations. You agree that, if you export
or re-export the Licensed Software ... You
are responsible for compliance with the United
States Export Administration Regulations..."
I can't tell if this wording creates the
problem you describe.
> The Lucida fonts bundled with Plan 9 are definitely
> not free, but nothing compels you to use or
> redistribute them (they cannot be modified or
> redistributed except as part of Plan 9).
"2.2 No right is granted to Licensee to create
derivative works of or to redistribute (other
than with the Original Software or a derivative
thereof) the screen imprinter fonts..."
Looks Ok to me.
Your summary of issues with Plan 9 license is at:
The current license is supposed to be stored at
I include a copy of the version I read from for
this email in footnote 3.
The md5sum checksum for the version I am using
for this email is f8be6752dae66936309f85b457c9f487
This version includes the text "Version 1.4 -
09/10/02" at the bottom. However, two posts to
comp.os.plan9 suggest that this is misleading:
Apologies for the length of this footnote,
but, as should hopefully be clear if you
read footnote 2 above, I felt it was worth
trying to keep this on the record this way
to reduce confusion if someone later comes
across this post.
The remainder of this email is the Plan 9
