What's the difference between solo mining and P2P mining?
p2pool is a mining pool, but the coin are directly mined to your own wallet address, so no Coins on the server. And you can encrypt your wallet to be secure. If the diff is high, then you can't mine solo anymore, so you need a pool, and p2pool is the nearest to solomining... here you find infos about p2pool
