[NMLUG] Re-displaying running apps on remote machine?

[peter at espen.net (Peter Espen)]

This is essentially the same as asking:

I have a telnet session established between machine A and machine B
and I would like to "unplug" the connection between A and B and
reestablish it, in place and unmodified, between machine A and machine C.

Mechanisms like VNC, etc are going to be your only option here I think.
