Is it possible to set up a VNC server in Xubuntu and use the VNC Viewer on the n800 to view it?

At the moment I just need to know if it's possible and can be/has been done before I dig into all the various bits of info available.
In short I need to know if I'm wasting my time trying to get it to work or not.

I'm using Xubuntu 9.10 (Karmic Koala) and the latest Diablo OS on the n800.

rDesktop is the one app I miss the most since giving M$ the heave-ho and I'd love to have the functionality back.
