Open-source Dance (Welcome: Contributions or advice)

I'm starting a website to provide "open-source choreography" - a place where people can post their own original choreography, with the agreement that it may be used, reworked, performed, etc.

I posted about this a while back: in the previous version, my site was more of a YouTube clone. I abandoned that idea, since I didn't want to deal with the legal issues of the music itself. This new version will be more like a blog, linking to YouTube videos instead (since YouTube has everything in place to deal with copyright issues).

What do you think? Any suggestions? Anyone know of anyone who might be interested in contributing choreography to this project?
