I've got Cygwin on my work box for using GCC when I need to do something that I can't do on the shared machine (if the cpu usage goes over 30 seconds on the pair.com account, it will kill the process... for good reason).
At home I just use PuTTY and ssh into whatever machine I want to use - but I can't use the graphical stuff (assuming you are suggesting for graphical cases - hence XFree86).
I haven't tried the Cygwin XWindows though - maybe I'll give that a shot. I've used VNC in the past for basic stuff - checking when rendering is done and such, but not XFree86 over the net.

Thanks for the tip.

(for this particular case, I've found a way to side step that need (Gimp scripting) for now, but might find down the road that I will need it, and will keep it in mind)
