Given the state of flux that VoIP is in right now regarding E911, your
best bet may be to set up the PBX at each site to route 911 to a bank of
two or three outgoing POTS lines.

(I will be very interested to find out what you eventually decide. In 
addition to the work I'm doing at JustThe.net, I'm working at another 
California school district, and our assistant IT director is talking about 
possibly going VOIP in the next few years.)
