Isn't that exactly the problem ipfs is attempting to address. What kind of solution do you want and why does this one not work for you? It's easier to discard someone else's idea than it is to evaluate it's merits. I'm not sure this is the solution but it looks interesting and it appears to interoperate with the existing Web via gateways even though the author does not make this clear early on in the documentation.
