IOW - NVRAM, solar panel battery recharge, modest CPU (ARM'ish or
something developed for mobile/PDA) - and the storage 'generally
hibernating' in some way until called for?

They will if the BIOS is set to do so..

See above. The bandwidth available to the average residence is the
single smallest knothole thru which all must pass.
An ARM-ish 'device' running any of the *BSD's or an appropriate Linux -
'sounds like' first-choice.
However - as an old Forth coder, I'd suggest that:
- none of the *n*x derivatives are all that well-suited to lying in
wait, near-as-dammit powered-down AND waking 'instantly' AND just not
What I would *want* to use is a PLA 'hardware' state machine.
What I'd settle for is a bespoke Forth - configured as essentially a
'state machine' (Canon AE1 camera, microwave ovens, et al).
Or even JOVIAL on an RCA 1802 derivative (as used in the F-15 fighter
for wehat 30+ years?).
IOW - your 'server' here might be a modified GSM handset or PDA....
It coudl then 'wake up' whatever else was called for - be that the door
locks or the salvaged 300 megawatt AN/FSQ-7 in the annex...

There you go - it ain't the technology that's at fault - it's the misues
- in that nearly every 'designer' thinks his disk-to-screen b/w or LAN
to screen b/w will hold true for some poor 1 mbps or even dial-up client
on the 'net.

Fibre has a deeper penetration into metropolitan Asia (which has few
'suburbs') than it has in suburban USA / EU (which have fewer
residential metro centers than Asia).
Far less old copper for the bean-counters to try to preserve.
AFAIK, Hing Kong was the first major city to go all-digital - and is
more populous as a 'city state' than many entire European countries or
even several entire US states. See also Shanghai - with a 'city' GDP
about 20%+ that of *all* of India.
My b/w in HKG - or to our other house in Zhongshan - is superior to what
I can get adjacent to Dulles Airport in Northern Virginia, and at half
The Americas and Europe have long since lost the lead in connectivity -
be it mobile comms, WiFi, or wire/fibre.
They just haven't yet noticed.
