So I would prefer NAT to eth1 or bridged to eth0. So no service runs
on outside network. Can I as root restrict this choice? Or can they
choose since they are the owner of the VM.

Rats! Forgot about that.  It's okay with my current setup since I
don't run a separate nfs server. But instead of running everything on
the server I was thinking about switching from ltsp to a diskless
client setup (100% local apps)
Since ddr2 ram is so cheap now and a c2d celeron e1200 is $55, one can
buy a nice cheap diskless client today. Problem is a diskless client
would need to mount home over nfs. Which rules out having a VM since
kids could change their uid in the VM.

Thanks for the reminder Les.
