Re: Deja-vu all over again
"My first job 25years ago was at a Philips spinout that was going to connect all your household appliances (or at least all the Philips ones) with a network that ran over mains wiring."

"After all the bold visions of your washing machine talking to your cooker to find out what you had spilled on younr shirt, the only non-laughable application anybody could come up with was having everything sync its clock correctly ever spring/autumn"
Neatly illustrating the "What do we use it for?" angle.
M2M is tricky because it takes humans out of the loop. So it has to be something people want to do but may be difficult for a human to keep up (maintaining safe car separation at the exact safe stopping distance for the vehicle speed and road conditions) in a way people are comfortable with.
How about a smoke alarm that shuts down all gas and electrical appliances (or their sockets) in the room its in when it detects smoke? Burglar alarm warns other appliances the property is now vacant so the power shower you left on shuts off. How about cars that automatically slow down to allow buses to pull out or traffic lights that tell vehicles their state and how long till their next change. Just an advisory but the potential effects on average road speed (and fuel consumption) could be huge.
The only actual M2M applications I'm aware of are things like industrial machinery monitoring, where sensors detect excess wear and book service appointments most spectacularly jet engines on airliners. Likewise vending machines reporting they have run out of brand X cans (eliminating 1 driver and their vehicle can deliver big savings over a year).
