Remote 'viewing / control' of X Windows

[Marc G. Fournier]

I'm dealing with a situation where I'm migrating ppl over to using X vs M$ 
Windows ... I'd like to be able to help them out remotely, similar to how 
I can with VNC for Windows ...

Is there something similar for Unix that would allow me to 'piggyback' in 
such a way that they're X desktop is an xterm on my machine, so that I can 
move their mouse around, show them the steps to do something, etc?

Thanks ...
