This is a problem we're trying to solve with MemoryCoin - decentralized mining by using commodity hardware and distribution. It's already possible to pool mine direct from the GUI and we're currently looking at integrating P2Pool with the client for increased decentralization. http://memorycoin.org/manifesto/

Efforts are funded by payments made in the blockchain voted for by the shareholders (coin owners). http://btcgeek.com/memorycoin-trying-something-brilliant/
