Logging into X remotely

[Piers Kittel <edinfo-list@biased.org>]

Hello all

Is it possible at all for X on a computer to log in another computer 
remotely?  I.e. one computer has XDM and WMaker on it, but without an 
XFree86 server, another computer has a XFree86 server, the computer with 
WMaker on, logs on to the XFree86 and shows the XDM login dialog box, 
and then logs into the server, and see the whole display just as if it 
was on the other computer?  A bit like console views over SSH?

Thanks very much for your help in advance
