# This program demonstrates how to connect two Vizard sessions
# together using the network feature.  This only requires that
# two machines be in the same network domain but does not
# require TCP so the computers don't need IP addresses.
#
# On each computer, the other user is represented as a robot.  When
# the other person moves around, you'll see the robot go.
