Potential for high frame rates
With a bridged connection you can have many parties connected.
Through the bridge that our friends at the New York Institute of Technology have we can connect with Netmeeting, and other IP based systems.
Cons:
Uses an ISDN connection (Expensive $80/month for 128K line)
Equipment expensive
Need many lines for the fast frame rates
Examples:
PictureTel (We have a Swiftsite (CS760XL now)
VTel (We have friends who use this equipment and we can communicate using our PictureTel equipment.)
