The real problem is the copyrighted material. I personally think it's perfectly OK to share revenue with your users if someone else signs up for your service and downloads something that you've share. MegaUpload makes a profit from people buying Premium because of a certain user and they reward them for that. If the copyright-topic wasn't an issue, this would be quite a nice business model (at least a kind of fair one). But this revenuesharing thing encourages people to upload files for a mass audience, and that's the reason why this doesn't work.
