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. <a target="_blank" href="http://Nomachine.com">Nomachine.com</a> used to have an example server you can connect to and give it a try. _______________________________________________ xorg mailing list <a ymailto="mailto:xorg@lists.freedesktop.org" href="mailto:xorg@lists.freedesktop.org">xorg@lists.freedesktop.org</a> <a target="_blank" href="http://lists.freedesktop.org/mailman/listinfo/xorg">http://lists.freedesktop.org/mailman/listinfo/xorg</a> </div></div></div> </body></html>
