i agree, there's already a n-factor multipool out there, they have only vertcoin and panda listed (and the latter is disabled for now), but if the coin becomes profitable, they will add it and start the multipool businness.
switching away when diff is high.

they have 161 Mh/s on vert as of now, the pool is trademybit

maybe even i'm going to send them an email to list execoin, it's good advertising after all!
