No. The problems are much more than the IP address. CU-SeeMe
wants to listen on 7648. The host running TIA can only have one
process listening on that port.
CU-SeeMe puts the host address in the data portion of the packet.
Since the address the end user is using is not really the address
of the host, this needs to be patched in every packet processed
by TIA.
There is no work-around.
