I think a few of the individual solutions are there to finance a studio or production but there isn't a platform that brings them all together. Most people will only have access to Fiat currency for at least the short-term future. A platform must take fiat from investors and audience members, peg that to individual tokens and then serve up content from decentralized storage (to prevent piracy) and pay out investors. I think a system which is built to handle the whole process would require a number of individual tokens. You could even combine mineable tokens with pre-mined tokens if you think about it. I was working on a flowchart for it last night and it spun my head around three ways to Sunday even thinking about the logistics. I do think it will be done though, just not now.
