Well, those admins should be shot^H^H^H^H^Hbeaten with a stick really
hard, or moved to an other position - the helldesk propably...

I don't suppose that many such environments exist, especially such where
the service provider NATs his users. (OK, it happends here often, but
well if we call a service provider someone who uses standard WiFi...)

IMHO a better problem to work on would be an automatic migration of
xsessions between servers (eg. when server load > max, but it would
require much more than just )...
