I don't see how crowdsourcing compute would be possible without giving access to all the data being crunched, which would be a complete deal-breaker for many (most?) businesses, I would imagine. So unless someone can figure that part out, it's probably a non-starter. With disk space, you have the issue of liability—what happens when someone decides to store child pornography on my hard drive? That's a more solvable problem, but I'm certainly not envious of anyone who wants to tackle it.
