The Artists Bay?
What about one with deals with companies but where you either have to share up to a ratio of say n:1 (n=10 or 20 or whatever, hence fix their distribution) or pay say "more than the average" to not be forced to do that?
With money going in being distributed to those who contributed their work (maybe over number of downloads but then again I guess people would cheat.. so - Yeah. Maybe not a good system after all?)
Sure there must be a way to charge a reasonable "media fee" and then provide a competitive "media access"?
