Abstract
The invention concerns using multiple computers to hold a conference. Under the invention, an application program can run on a single computer, yet remote participants can issue commands to the program. Remote participants can watch the program operate, because the invention replicates the display window of the running program onto the displays of the remote computers. Any participant can make annotations on the participant's own computer display. The invention copies the annotations to the displays of the other participants.
