I'm a lurker, since I don't have the time to get involved with something like this, but considering the number of people involved and the difficulty in coordinating a play session, wouldn't it be better to just go the PBEM route?
With PBEM there's no issue with OOS, no need to coordinate play sessions, and it's easier to set up. The problem would be that with so many players it would be a rather slow pace, but OTOH if everyone could get together for "power sessions" things could move quicker...
