I've been trying to zip together what I know about free online collaborative projects (like free software) and commercial free culture projects (like the just-released "Sintel" from the Blender Foundation or "Sita Sings the Blues" from Nina Paley). It's easy to get lost in the logistics of such a production. One of the questions I'm bound to be asked is "How do I know I'm going to get paid?" Artists have a strong fear against being "exploited", though they're often less clear on exactly what that means. A little bit of examination, though, shows this may be a strength of the "Creator Endorsed" free culture approach to marketing a work -- it makes fair payment a matter of personal financial interest to the publisher, as I hope to explain here.
