so there's all sorts of weird new access tech, like there's two zigbee
nets in my house alone, plus community mesh - what do people measure
on those? Most the hard work in last few years has been on
pay-per-use nets or broadband tech of the legacy (adsl, cable modem,
and cellular data)  - but i guess the question here is what are the
weird and wonderful lashups occuring out of cheap & cheerful, as well
as the ever onwards march to fiber to the eye+ear, no?
