I haven't seen any ILEC offerings of xDSL for $50 per month or less here in the Northeast. If you can get that where you live that is great (still a lot more than $30 per month from Media One but getting there). I must take exception to your argument about throughput for cable vs. DSL. Clearly, cable is a shared medium in the access and most HFC networks are designed such that one node serves 500 homes or less (there are many, early deployment, HFC networks that serve 500-1000). You must remember that an HFC node is divided into multiple quadrants (usually 4) so that there may be 125 homes passed on a given shared facility. Assume even a 20% take rate (very high) and factor in peak usage and you'll see that throughput won't be a problem for some time if ever. You also state: "With DSL, its your pipe; its your own private road to the Internet backbone." Nothing could be further from the truth. DSL lines terminate on a DSLAM (DSL Access Mux) in the CO where all the traffic is aggregated for hand-off to the WAN. At the DSLAM there is statistical muxing taking place and it is up to the service provider to determine the level of over-subscription that will be chosen which could be 10:1 or greater. So DSL is shared too. The dedicated part is on the access line only. Bill
