It would be very neat for pyramining to start a p2pool proxy available for pyramining users that allows us to set our little miners to autamatically deposit on pyramining with the most reduced fees. I'm not sure about pyramining deposits' most inner workings, so I do not know if it would be good to pyramining or not.
I am working on this, however mining to a remote p2pool may not be the best solution, the network latency could reduce a bit the mining efficiency, it would be better to set up local p2pool nodes for everyone who wants to mine on p2pool (which is a good thing, in general), and if you want to invest your mined bitcoins in pyramining you can just use set a deposit address as the p2pool payout address.
