One thing a lot of people are forgetting, is that such a service must
not cause interference to a licenced service and must accept
interference from a licenced service.  This means that if there is, for
example, interference to a "Ham" or from one, it is the reponibility of
the power company to resolve the problem.  Unfortunately the neighbours
are more likely to blame the Ham, should they experience interference.
Then there are the various mobile radio services, aviation, short wave
broadcast etc., that have the potential for interference.  The same
situation occurs with the cable TV channels, but the cable companies use
coaxial cable, which is designed for this use and does a good job at
preventing leakage.  The same cannot be said about power lines.  As far
as it being "old news", nothing can be further from the truth, as it's
an ongoing problem in the U.S..
