Mike,

I wonder how much bandwidth, out of the hundreds of channels arriving on the tv cable, is actually required for one channel.

WRT VOIP: I don't know how they can bill for it. I've been working on www.webtrain.com's networking for many months. I'm tunneling video, audio, and several other data-streams simultaneously over an HTTPS connection and I don't see how, as a practical matter, ISPs can prevent that sort of (ab)use of the protocol. :-)
