My last comment about BPL was troll rated. That moderator doesn't know his ass from a hole in the ground. I've had close contact with a particular BPL sales team. I've heard them talk to their prospects on the phone. I've heard them lie about the interference potential of BPL.
BPL is a technological solution to a problem that has already been solved by wi-fi and various other means of providing internet access to the home. BPL is also bad physics. Using a single wire to send a signal and then saying that it won't cause interference to existing services is a failure to understand what Mr. Maxwell wrote in his equations oh so long ago.
Furthermore, letting the power company provide internet access is just bad policy. They are already a monolopy in one service, why let them try for another?
