Not being a legal buff myself, I doubt I would be able to make any valuable contributions, but I think it might be an idea of maybe getting some of the universities involved.

Maybe drop a mail to someone like Derek Keats (Not sure whether the link will come out properly but hey!). He’s a bit of an open source nut, and might have some law prof. friends at UWC. (Don’t know the guy myself, but have come across him before)

I think it would be great to get the legal community into the whole spirit of open source. Good luck!
