[RFI] ECM...etc.

Our CT power company just installed a load-shedding device on our air 
conditioning compressor that lets them shut us off when they reach 
capacity.  They give us $20 a year for our kindness. We had a similar 
arrangement in California that paid more handsomely.

Anyway, these devices seem to be controlled by some kind of digital 
link.  I assume this is over the air, like a pager transmitter, but it's 
an example of what a household data line could do in the future.
