That is SO phracking cool.  So, in essence, two people can play Infocom,
Scott Adams, Adventure, nethack, or any other text based game together?

Ytalk is awesome.  I first ran across it in 1991 while I was working as the
night shift / weekends/ holiday shift computer operator for San Francisco
State University.

It was my first (legal) experience on a Unix machine.  We had an Ultrix
machine running on a PDP, and I found ytalk while playing around with "man
-k".   Ytalk is really cool...
