My original question is still unanswered ...Can any of NeatX, X2Go, FreeNX, NoMachine NX or others use an *EXISTING* X session already in use by the user sitting at the computer instead of spawning another in-memory server-side session?

I can't tell you specifics about how its protocol is built, but NX is not passive like VNC. I believe NX actually contains a complete X server in the client program, and uses its protocol for very efficient display. It is very much better than RDP or VNC. I've never used WebEx so I can't say, but NX is almost like you are sitting at the local terminal. Even smooth scrolling in Firefox looks normal over a slow DSL line. NX can also act as a proxy for RDP or VNC from one local machine to another, and use its protocol for that, though it is not as efficient as a native NX session. Nomachine.com used to have an example server you can connect to and give it a try. _______________________________________________ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
