VNC passes session traffic "in the clear" (without encryption). While you
can tunnel VNC in SSH, it is clumsy to set up and not very efficient.
NX/freenx uses SSH for transport (strong encryption) and is uses bandwidth
more efficiently as well, using aggressive compresstion and caching to make
the sesstion more responsive.
Opening (port forwarding) the SSH service to the Internet can be a security
problem. If possible I would restrict which users can use SSH and make sure
those users have "good" passwords; not vulnerable to dictionary attacks.
Also make sure that SSH is up-to-date and keep it that way, plus turn off
VNC version 1 capability.

The district is behind a firewall and the server's eth1 has a static IP: 10.x.x.x - what is the easiest way of allowing them to log in as thin clients from areas away from the lab? VLans are not viable, and their laptops are running XP. I should be able to burn a cd with enough info/resources for them to log in, no? DSL?
