It's a more echonomical and reliable alternative to BPL that doesn't polute 
the ham bands.
Unfortunately, Michigan, which is where I live, is in deep financial doggie 
do. They are going for the big federal grants to bring in  money and that 
includes BPL. We don't need BPL in the bottom 2/3rds of the lowe peninsula 
as most of it is heavily populated and most of that is served by high speed 
cable, DSL, or WiMax, but that is the area I see as likely to get BPL if the 
state gets their way. Those are the areas where the pilot projects are being 
run.  It is also the area with the most hams to have interference and to 
cause same.

I do have to admit that from what I've seen, BPL is getting better and most 
of the groups are willing to work with the hams. Not all but many. OTOH Most 
of the power company ventures into BPL Internet service have closed down 
incuded the big one in Cincinatti.

As for antennas:  The better the higher the gain the farther we can hear BPL 
and the farther away we can interfere with it.
In the early days were the systems were highly susceptable to ingress I 
would have had a strong enough signal to shut down a system over a mile 
away. My 75 meter, half wave, center fed sloper on Europe is less than 75' 
from the pwer line.
