With a $15,000 'Annual Participant Membership Fee' to get the specs,
I'd doubt it.

It is not clear from their website that any products exist to be
supported. Also, unless they are totally braindamaged, I would imagine
that all of their products will appear to the PC to be just like regular
ethernet network cards, but use a different physical transport layer.
Hmm, I wonder if I will be able to run tcpdump from my electrical outlet
and listen to my neighbour's network traffic, and take over their X10
appliance controls ;-).
Cheers, Andreas

That would show a disappointing lack of imagination. Given the people
who are there I'd hope it becomes another connector off the standard
ATX PSU 8)

Quick down to the patent office with mains firewalls

As someone else has already responded. Closed source standard so I'd guess
unlikely to become a true standard. Seen many variations before and they've
all crashed and burned. Whatever happened to the NorWEB field trial ?

More interesting could you hack into the protocol for reading the electricty
meter remotely ? Spoof the meter and save a fortune in power bills!
Worked nextdoor to a remote meter company once and it was a problem they
took very seriously.
Still puzzled by the European political standardisation of the power supply.
Politics says 230V yet my AVO still reads 240V RMS in the UK and 220V in
Germany ? Still it also says 50Hz and I'd swear I only get 49 and a glitch.

Encryption?

The formal spec is something like 230 V ? 10%. The value 230 V was
chosed exactly because both the 220 V and 240 V mains systems could
comply without change as long as they regulated their voltages more
tightly than the spec required. Since the main reason for the fairly
wide error bar isn't variation in generation, but remote locations
with long transmission lines (how much voltage drop between the
nearest and the farthest tap?), this is mostly a non-issue. It might
have required adjusting transformers in a few places that serve just
such remote locations, or the installation of buck/boost transformers
in a few places. In urban areas it should have made absolutely no
difference. Maybe they'll start using 230 V for new installations,
but somehow I doubt it.

Yes. Encryption is part of the standard.
