I've concluded that the existing cable network infrastructure limitations pose a considerable obstacle to the viability of video conferencing - assuming you want something better than a novelty.

Medin's now well known response to the cable co.'s idea for a broadband cable network applies here: " There isn't enough bandwidth in all of Christendom to satisfy the demands…". The strategy of bringing the data closes to the user via caching computers and regional data centers is the concept from which @home's network was conceived.

Video conferencing just doesn't fit the network model well. The biggest problem is the upload speed cap (128kb/s) but others are jitter (if you want smooth interaction) and then download bottlenecks in the local node.

What does fit the network model well is Video on Demand and video e-mail. Streaming video to a lesser degree because it doesn't utilize the caching computers and RDC's.
