It seems to me that the Xerox user interface would be ideal for letting
several users communicate over a computer.  Two or more users could link
to a single workspace and would have identical images on their terminals.
Both could type simultaniously, hopefully in different windows.  If an
expert was helping someone than they could communicate through a "talk"
window with an editor, the advisee could run things and point out the
problem to the expert, and the expert could also run things and explain
the problem to the advisee.  All that would be necessary to add this
feature would be the ability to support multiple mice and keyboards and
to treat several CRTs as one.  The major problem is that the interface
to the CRT is usually at the bitmap level, so a very high bandwidth is
needed.  A high speed network would be necessary for reasonable performance.
Has this been done already?
