Sorry, what's "ECM" mean?
Lets take "sweeten the deal by providing the customer with wideband access"
out of the equation - its not unique to BPL or the ability to provide smart
house energy management.
Just considering "hardware deployed in house" in return for "lower
electricity rates", it all comes down to up-front-cost vs. payback period
and cost of money. I doubt many consumers will invest for a payback period
exceeding 3 years, so that puts an upper limit on the up-front hardware cost
given typical annual electricity costs.
Can Zigbee be retrofitted into existing applicances?

Take a step back from the ECM issue for a moment...and consider what might
happen if you implemented Zigbee (802.15.4)...and/or homeplug...and wound
up with a smart house which permitted energy management--load levelling in
high demand periods in exchange for lower rates--plus remote monitoring
capability--plus outage & cet. tracking, and remote metering.... and then
sweetened the deal by providing the customer with wideband access.
At what price would energy have to be, to make that make sense? Oil at
$50 a bbl? $60?
