I wonder what price points are involved? I could see making use of the power sensor if it can sense devices that aren't just high-power consumers like irons or coffee makers. It'd be a handy way to tell if the TV is on or not, for integration with a home theatre and lighting setup. As in, it's
3am and the TV's still on, or it's 3pm and the TV's on but they kids aren't supposed to be watching it...But like anything else, if it's not reasonably inexpensive it's not going anywhere. The market wants pricing like X10 but will not put up with its complete lack of reliability.
