There will be so much capital investment by companies in BPL that the
courts won't dare to overturn the decision!!!! The FCC will cave to the
$$$ interest, if they have not already done so.

The answer may be to establish local HF nets, need to be local to keep
S/N ratios high, and get on the air during peak internet times and
simply shut down the BPL service at the consumer level. Let the
consumers complain about poor service. Then provide the defense of
non-licensed Part 15 devices etc.

Running 1 KW as the minimum power necessary to communicate across town
on 75 phone will certainly have an impact on local BPL users!!!

LOL - that would do it. But even 100 or 200 watts would be enough to
muck up BPL if there were enough of you in the city.
