 What I've done is roughly...

  - kept the "8 servers" model, each on a /21, with the "base" /21 used
 for inter-server networking

  - server "1" now takes the 2nd slot as well to make sure it controls
 the 172.18.16.x range (needed for activation) with mshbond0

  - which in turn bumps every other server one slot over

  - grabbed an additional /19 segment at 172.18.96. with 8K addresses
 for the LAN / AP network.

 Which means that the XS "1" has on its LAN port

  - 172.18.96.1 - the long dhcp range address. This is the main address
 to appease dhcpd.

  - 172.18.0.1 - the 'schoolserver' address where services listen

  - 172.18.1.1 - the address used for inter-server routing

 Along the way, I fixed various routing and netmask errors.

 The main arguable point -- beyond potential errors -- is whether the
 "8 servers" model  is useful long-term (probably not!). But we'll deal
 with that later -- when we have something clearly better.
