Only problem is that this/these sort of project(s) would entail an enormous amount of energy and effort to develop. And then you'd also need to ensure you have sufficient marketing clout so it doesn't just lay dormant. And then in the end it's a completely decentralized system. The idea of a creator sitting around skimming money off every transaction is not really part of this picture.

So it's not really the most enticing of projects to take on. Big investment, minimal personal reward. On the other hand, I think it will happen - eventually. We just need another Tim Berners-Lee type individual. Except preferably one that happens to be a brilliant engineer, salesperson, and billionaire.
