That's how time-warner is doing it here in Maine. However, they've
assigned voip to its own channel while digital channels occupy another and
hdtv signals are compressed and on another, etc. Its a 1Ghz system.
Everything on the system is IP including the control boxes. They also
have certain video and PPV on demand as well. Very interesting system
that serves as a model for the rest of the country. Whatever they do they
roll it out here first and this system totally rocks. I regularly get
downloads at 3Mbps.
