Oh, it may not be a P2Pool server, it sure sounds like one from the description of the payouts, though.
My pool (
http://limitedloot.org:6327 *is* a P2Pool, btw.

Oh, so you mean it's a PPLNS pool (Pay-Per-Last-N-Shares), pays out based on an average of a set number of shares. (Meaning that you have to mine for a while to increase your payout, and can be paid for shares multiple times).
On that note, the pool which supports the faucet is also a P2Pool instance, with a custom live-updating frontend
