Nice. I see that the P2Pools have a 10% fee that people should probably know about.
I'd like to add that it's highly recommended to add multiple pools to your miner so that they switch over if the primary one fails.
It sucks when your miner has just been idling overnight because your primary pool is under a DDoS attack.
Not sure about reaper, but with cgminer you just add multiple -o , -u, and -p combinations.
