    Anyone know how far off or how expensive how fast?
  2. 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.
  3. 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.
