[License-discuss] For Public Comment: The Contribution Public License

due to me being unable to find a reciprocal software license I'm truly happy 
with I've been working on developing my own:


I would - eventually - like to submit the license for OSI approval, but 
thought sharing it here, with this mailing list's audience, in order to gather 
feedback beforehand would be prudent.
The current draft is attached in plain text as LICENSE.txt and the license it 
in turn is under (due to it being derived from the Patches Back Public 
License) is attached in plain text as CHANGING.

What I wanted was a license that's as close as possible in spirit to the MIT 
license, except requiring any modifications to the software to be contributed 
back to the public under the same license.
After looking over the list of OSI-approved licenses there were three I could 
identify as being close to what I want, so here are my reasons as to why they 
aren't satisfactory for me:

Reciprocal Public License (RPL-1.5):
It's not only too long and complex for my purposes, but it also explicitly 
defers arbitration to Colorado, USA, which I cannot accept.

Eiffel Forum License, Version 2
While being sensibly short and concise it only encourages - but does not 
require - modified versions to be publicly released.

Microsoft Reciprocal License (MS-RL)
It's copy-left for things such as static linking, containers, etc. (section 3, 
paragraph A) and it deals with patents and trademarks.

I hope the above highlights that there's a particular niche that's not quite 
filled yet.

Thank you for your time,
