For anyone looking for another POLY pool that has some momentum, zpool.ca is a yiimp style pool, I've been using it for a couple weeks now.  Pool hashrate is 550MH/s at the time of this post, it's been growing and has been a good option for avoiding the suprnova pool without having to use a pool with low hashrates.

I like the idea of POLY so I'm sticking around long-term for this one.  Might even contribute to coding up tools or whatever might be useful.
