I'll have my pool up and running here soon. It's a sub pool to p2pool, payouts are daily on a proportional basis, tossing around a PPS as well..
It's not up yet, but will be soon.
www.PeerMining.usHow do you handle PPS with p2pool? I have an interesting idea but I want to know how you're doing it first

So far it's an idea.
I'm not looking to make this a profitable pool, just looking to cover overhead costs of running it. My PPS idea is pretty basic really. If there is enough market for PPS, then I'll setup another server, which will require me to colo another server and then setup pushpool or something of the likes (undecided) and simply just running a PPS with some fee attached to it all.
(Again, this is just an idea at the moment, am awaiting the results of the first pool before I just jump in head first with no idea of outcome.)
It's actually fairly easy to do just by collecting shares on one port and passing them to a p2pool instance on another port - ygpm
