Using the P2Pool share network for fast confirmations

[timando]

I read about P2Pool and it said something about making a block every 10 seconds. I'm wondering if you could use this to get faster confirmations, or would double spending still be possible?

That is within the p2pool network, that is pooled together to find bitcoin block.

Short answer No
