The latest Cringely column covers the potential for a new high speed broadband service over copper. Dynamic Time Metered Delivery from TelePulse Technologies (sorry they don’t appear to have a Web presence, all Google can produce is this HTML slide site) can provide 22 megabits per second out to homes more than 2 miles away. And you can combine wires to increase bandwidth. The upgrade path for the telcos is also relatively painless, requiring only an exchange of cards at the central exchange.
I am also encouraged by reports of other technologies such as Fast TCP, which also promises to give us super fast broadband over ordinary copper telephone cabling. Who needs fibre anyway?
