[RFI] ECM...etc.

Sorry.
Jetlagged.  That was supposed to be EMC...as in electromagnetic compatibility.  As opposed to ECM, which is electronic countermeasures.  
You make a good point about retrofitting appliances.   I would suppose that being able to add wireless isolated metering/monitoring to the electric, gas, or water supply would be a pre-condition.   Control of heating system and lighting, either automatically or remotely could have value for some
I can't imagine that having appliances interfaced would add value to my life.   Coffee maker?  Frig?  Stove?   Interfaced pantry reporting stock levels of items and generating a shopping list?   I don't think so.  
This is a major digression in one sense...but may be important to understanding what's driving the power industry's investment vision.    I haven't read enough yet to see what their magic motive is for BPL.
