@blueplanet:
Wouldn't it be possible to place a filter at your meter that would shunt
the BPL signal to ground for the whole neighborhood?
No, but one of the issues with BPL is that equipment connected to outlets
changes the configuration, and although BPL is adaptive, reliability of
full speed service at any location in a premises is not assured.
