I guess I was assuming this would be a separate box, firewalled from the 
LTSP network.  You could then set up multiple bridges on a single 
physical network interface on the VM server.  Maybe I'm not using the 
correct terminology there.  I've got 6 "tap" interfaces working off of a 
single physical interface on my VM server.  tap0, tap1, etc.
