Stripped-Down 7.04

[David Van Assche]

by following this howto on low fat clients and installing a real minimal
environment in the chroot as mentioned there + rdesktop. could work. I'm
going to test this myself as an alternative to running vmware from the thin
clients: seems like better use of resources.
