hypotethical question
if kano used his pool to mine with p2pool as a node, would it be more efficient mining fot his pool or not?
Interesting idea... however I suspect Kano wouldn't want to risk the stability of his pool software (I'm assuming you mean altering/extending ckpool so shares are distributed with/like p2pool).
I'd prefer to ask: What would need to be different within bitcoin to make solo mining feasible again ?
I suspect Smaller (not Larger) blocks would be the solution as it would give the 'small' guy (< 1Th/s) a better chance of an income......
