The effort that you've spent to dig into the details and research
all of these copyright and licensing related issues is very much
I must say that I also agree with your conclusions, and believe
it is a very good start on planning what work would need to be
done to change the situation on the affected portions of code.
Perhaps we should stick this up on the freedesktop.org wiki
somewhere so that people interested in volunteering are aware of
some possible things to work on.
Thanks again for spending your time investigating these legal
issues, as it is very likely to benefit the whole community.
