Sure, but personally I'm a fan of P2Pool's instant payouts when a block is solved AND a low variance.

That's why I wrote a proposal that would allow any P2Pool node to honor the work of either only the miners that find shares (as usual) or also the work of all miners that submit (low-diff) shares. https://github.com/forrestv/p2pool/issues/135

This approach would lower the variance at well attended nodes a lot and therefore might encourage many low-level hashrate miners to use P2Pool again.
Feel free to attach comments, improvements or even qualms.
