Dave,
Another aspect of BPL that doesn't seem to be getting very much
coverage is that some of the trial deployments cause HF radio
interference. The amateur radio community is quite unhappy about
this. More information at:

Some excerpts:
What is Broadband over Power Line?
BPL is the delivery of broadband Internet signals using electrical
wiring to conduct high-speed digital signals to homes and businesses.
BPL systems are designed to deliver Internet services using medium
voltage power lines as the distribution medium and generally use the
frequency range between 1.7 and 80 megahertz (MHz).
The Concern: Broadband + Power Lines = Interference
Because power lines are not designed to prevent radiation of RF
energy, BPL represents a significant potential interference source
for all radio services using this frequency range, including the
Amateur Radio Service. Overhead electrical power lines and
residential wiring act as antennas that unintentionally radiate the
broadband signals as radio signals throughout entire neighborhoods
and along roadsides. Interference has been observed nearly one mile
from the nearest BPL source.

Plug-In Internet Connection to Get Test on Long Island
By KEN BELSON
The New York Times
February 17, 2006
Customers love to grumble about their phone and cable companies, and
residents on Long Island are no different. But for those unhappy with
their service from Verizon or Cablevision, an alternative may be on
the way.
The Long Island Power Authority announced on Wednesday that it would
begin testing technology that provides high-speed Internet
connections through people's electrical outlets, a service that could
ultimately make a dent in a business now dominated by Cablevision and
Verizon.
For several years, utilities across the country, including Con
Edison, have been examining the technology, known as broadband over
power line, or B.P.L. Companies like Cinergy in Cincinnati have
started selling the service, which requires that customers plug in
special adaptors that link to their computers via Ethernet cables or
wirelessly.
In addition to generating new revenue, the technology is attractive
to utilities because the two-way Internet connections let them more
effectively monitor their networks and their customers' electricity
use. Some companies are also using the technology to provide Internet
phone and video services to residential and business customers.
