This would be for things like music and film only, with perhaps some of the money raised handed over immediately, and the rest held until the project is complete. And, since the musician/filmmaker/whatever has already been paid, a further stipulation on receiving the rest of the money could be that it's released under creative commons license, or something like that. Seems workable to me. (Either way I'm confused about the downvotes.)
