Multi-mining in pushpool/p2pool?

[struck]

I want to create a pool that mines multiple currencies and switches between them at different times. What I am wondering is if pushpool can act as a proxy to a remote pool? Or if p2pool can do the same? And of course support multiple miners.

So instead of pushpool -> bitcoind for example, I wish to use a remote pool. p2pool can act in such a way but I am not sure if it can associate shares / income to certain workers (not auto-payment to a bitcoin address).
