One issue with the through-the-outlet networking: I was working
with a submetering firm a few years ago and we were told if there are
transformers along the line, you lose transmission. (ie, power
modulation doesn't travel passed transformers) I have thought about
this issue for myself because not all power in our house is on the
same phase. (power is transmitted in three signals each 120' out of
phase so the total adds up to zero.. sin(x)+ sin(120+x) + sin(240+x) =
0.. once only half the power in our house was down because only one of
the phases wasn't transmitting.. it baffles me how they can then meter
both phases on one meter)

You have 3 phase in your house?? Where are you that you can get that?
