Anyone think we should put together a community bounty fund for an improved GPU miner?
I'd rather pay for a true CPU only solution.
Impossible. What you CAN do, is make GPU simply not worth it. But it's a really stupid idea - botnets will then dominate the hashrate if your coin has any value.
EDIT: Shit, what am I saying, I'm better at CPU dev than GPU dev. Disregard my last.

Cpu is the way to go and I can think of one really good example of this with drops on rewards when hash rates get higher.
