Once AM starts self-mining again, I would really love to see them use p2pool.
I expect that more miners would jump into p2pool if p2pool's share of the total hashrate is greater than now (i.e. greater than ~1% of the total hashrate). This would really be great for all of bitcoin. As a side-effect it would also once again paint AM in a very positive light.
Either this or start our own pool that mimics the payouts of Ghash.io. I think most people would like to get off of Ghash if there were an option as profitible to hop into. Running a pool would be a really nice way to get continuing income as well. With the hashrate we command it shouldn't be hard to get the ball rolling on a ghash competitor, maybe even just straight up buy out a smaller pool that already exists.
