Hi Eric,

split it into three virtual channels that use 50/20/10 Mbit. I'm sure that theoretically it could be done,

If I understand you correctly, the multiple signals are to be sent on one frequency channel. An old fashioned TDMA scheme should suffice to provide the multiple signals. It seems to me this is just a restatement of the mux/demux problem. The 53 byte ATM-type muxing should be robust enough for streaming video or voice on multiple channels, as long as bandwidth is not constrained.

Is there any other way to prevent one ISP from infringing on the
performance of another except by assigning physical spectrum to each ISP? VPN protocols or PPTP or L2TP could possibly be called upon in a packet switched environment. CoS assignments, Password and firewall protection would provide the requisite control from one carrier stomping on a competitor.

It's all theoretically possible as you say, but I doubt that subscribers are going to want to pay the cost of scaling down backbone solutions to the individual subscriber. $500 per month with good customer acceptance might just cover the development of such schema.
This of course is just a WAG. But it is not a trivial problem and I'm sure the MSOs are loath to try such a convoluted plan.
