I completely fail to see why we need the DHCP server to get the IP address 
of the nearest MPP or get the optimal path to and from it.

As for the multiple radio scenario at the schools, you can address that 
with two different ways: bridging  between the interfaces on the server or 
-if you want something quicker-, use a different autoIP range for each 
channel.
