I'm not sure how they would do that, because you need to give permission to 
the "other box" to display on your local box.

The "normal" way to do this is to:
1. login to your local box
2. in an xterm, run "xhost +other_host"
3. ssh/telnet/rsh/whatever (in order of preference) to the other host
4. set your $DISPLAY env.var. to your local host
5. run your client app(s)

There are some changes to the above if you have different user names on the 2 
machines and so forth, but that's basically it.

HTH,
