California has mandated that all power meters be switched to remote  
reading.  Right now there are 2 pilot projects and the full rollout  
should happen within a couple of years.  There is also a program in  
place that installs a thermostat that can be remotely set by the  
utility so that on hot days they'll turn off your AC for a short time  
to save power.  I think we'll see a whole lot of this stuff in the  
next few years.
