Have you considered configuring the internal nic to listen on two ip addresses, lan and wan? I think you said you are locating all of the XS machines centrally, so this might be an option depending on the networking infrastructure you have in the central location. What would happen if you changed eth1:1 in the network-config script to eth0:1? If at some point in the future you locate the XS at the school, then you might have an AA on a usb port and not need the second nic anyway.
