Actually i think that RDP runs alot better atleast on windows pcs.
if you want to port, maybe you should look for source code from one of the android ports, but the problem is that it has to be ppc code....
VNC and RDP can be used to control a remote computer.....
BTW, with both the Debian and Ubuntu we got running with ASBESTOS Installer you can type this in terminal
apt-get install rdesktop
and use that to rdp to you windows computer.
rdesktop 192.168.0.2 -f
192.168.0.2 being you own ip but i guess you know this... just stating the obvious if someone else reads this on a later point.
-f is for full screen!
alt+ctrl+ enter to exit of full screen
