Just a random thought on FAQ, Q: Can I use WFA media/wffusion/q2wf for another project?
While GPL has nothing todo with the media and it can be closed or whatever. All code that links to GPL code must be 'free' (whatever the definition of that would be), but if Q2 is LGPL then it would be k.
I thought the A: ... needed some rephrasing with this in mind and it made me think of OSML Open-Source Mod License, but then again you stated that you want it closed.
