Copyback license (for discussion)

[Chris Zumbrunn]

Since I posted an earlier draft of the Copyback license, I've 
incorporated feedback, improved the language of the license to avoid 
using the same words with different meaning and reduced it to be even 
less verbose.

The Copyback License is generally more permissive than the GPL but also 
contains restrictions that are incompatible with the current version of 
the GPL. It requires that modifications and additions are shared even 
if the binary/source of the derivative work itself is not distributed, 
but like the BSD-style licenses it allows for use in proprietary 
products.

It is closest to the Reciprocal Public license, but non-verbose, more 
permissive and far less anal retentive.

Cheers and thanks for any further feedback,
Chris
