I need to remotely present different applications that I run (whether firefox, openoffice, or a media player) to a remote X display. So, for example, if I launch xcalc on my machine, I need it to launch on machine2 as well (that is, be displayed on), and if I press the #1 button in xcalc on my display it gets shown on the remote display, too. And then if I play a movie on my screen it would play on the remote display, too. If it could just display my whole screen, that would be OK, too. Now I know there's VNC, but I don't think the VNC protocol is efficient enough.

In the Windows world, I used this device:

Vista provides generic capability natively:

Now we're leaving the Windows world and traveling to the Linux world but I can't bring my LiteShow with me. Any ideas on how I can ultimately accomplish the same, even if I have to ditch the LiteShow altogether?

Reading your second link, it talks about using the Remote Desktop Protocol, which is basically the Microsoft equivalent of VNC.

You could use xrdp if you wanted to stick with RDP, but VNC is in general going to be better supported in Linux, and even in Windows... as long as you don't have Vista.
