Anyone know how far off or how expensive how fast?

There have been several trial services running in the UK over several
years, but there's no widespread deployment as far as I know.
Currently there's one running in Winchester, and IIRC a colleague
who looked into it said the speed is 2Gbits/s.

I rather imagine the differences in final power distribution to homes
in the UK and US would make it much less economically viable in the
US -- typically in the UK some hundreds of homes run from a final
stepdown transformer verses less than 10 homes in the US in areas
where powerline distribution is likely to be most effective. The cost
of the equipment at the transformer and the network connections to
such kit is thus going to be much higher per home in the US.

oops, typo -- should read 2Mbits/s

I don't know that I'd agree with this, because I know that the local
power company dopes remote reading of house metering through the power
lines, and they've managed to sign on the Water Bill folks as well. And
this is at the 120/240 side of the transformer (usually with a 14.4/24.9
kV Transformation).

Expensive, most certainly. But obviously achievable.
