Ghezz...

if all you wan't is X forwarding just use X..

on win98 etc
get cygwin www.cygwin.com

and install the X packages
(it seems like the installer hangs if you click on the X section ... but it doesn't... just wait for a while (10 min on slower boxes!)

then
turn on xforwarding... on the server
(I think the command is something like xhost +ipaddress or range)

then on the computer you are using as a terminal type something like:
X --query ipaddress of host

www.subverted.net/wakka
and search for x forwarding... Or... goto google and type X forwarding in...

I think Knoppix uses LTSP to serve the images that it shares... and then nfs mounts the cd-rom

It's usefull for rescuing an entire computer lab in a pinch... geez..
