"From those outlets pour streams of digital video, interactive games, online radio stations and services familiar to people who use cable or telephone modems to get high-speed Internet connections.

"The only extra equipment a consumer needs is a modem that plugs into an electric outlet and connects to a computer or Internet gadget. About the size of a deck of cards and costing less than $70, the power line modems are already in stores for use in home computer networks that use electric wiring.
The wiring in the test home is more than 40 years old and required no changes besides the modems, Birnbaum said."
Interesting... I know you could use power wiring for networking, but internet access too... good idea really, since every house has it.
