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.
