Maybe a spherical cow :-). In the real world we still have to support IPv4-only devices for the foreseeable future, so any device which speaks a new protocol will have to flawlessly speak the old one as well. You might be able to have a new protocol device talk to an old protocol one through translation but that just moves the complexity around, its not any less complex than just continuing to run the old protocol, which maintains full compatibility and fidelity.

Do you also still support SSLv3?

Haha, yes! I have a copy of Firefox 20 with Flash 18 running in a WINE bottle set to never upgrade so I can contact appliances which have old SSL which is no longer supported by anything modern. Those devices aren't going away anytime soon so we have to maintain an old environment to be able to talk to them as the world has moved on.

Great. I'm sure you are also keeping you old analogue mobile phone around, just in case. :-)

Not mobile - fixed line, but yes.

Our phone system is powered from the exchange, not the home, power supply. So we have a fixed-line phone plugged into the wall (plus all our cordless, true). But that way, if we have a power outage, we still have a phone line.

Somebody tried to nick a 50KV power line near here a few years ago, and a large area was without power for about a week. Cordless phones died instantly without power to the base station. How long does a typical mobile battery last nowadays? With all these smartphone functions I can flatten mine in a day (and if the local mast dies it'll flatten itself transmitting at full power trying to find a mast!).

Okay, we were about 100yards outside the power fail area, but if we'd lost power our phone would probably still have worked because the local exchange would have had an emergency generator.

Cheers,
Wol
