Interesting article. It would be great if someone could develop a solution that would help mining to back to the old days of a truly distributed network. Perhaps if each block then set the hashing algorithm for the next. Currently it's a form of SHA256 every time, which is why miners can manufacture chips specifically for mining.

I don't know if this is technically feasible, but could the hashing algorithm change from SHA256 to, say, a 432 bit hash, then a 335 bit, etc. algorithm? If so, then you'd have to go back to CPU mining. If every desktop got back to mining, no large mining outfit could quickly match the masses and it would stay distributed...for a while.
