Has anyone been able to share a Linux desktop using FreeNX?

By sharing a desktop I mean that two users can work on the same desktop at the same time on a remote machine. I used to be able to do this under Knoppix with vnc-server, but that has apparently been replaced by FreeNX. Although I've been able to create individual FreeNX sessions, I have not been able to figure out how to share a desktop between two or more people.

A google search of site:knoppix.net and site:nomachine.com didn't turn up any hits.

Any pointers to instructions gladly accepted. BTW, I 'm using Knoppix 3.8.2, but solutions using any Knoppix version would be helpful.
