	If you just want an alarm/phone call system, Radio Shack, among
others sells one, cheap $70?
	If you want alarms/phone call and power shutdown, there are these
SAM units advertised in the back of Digital Review and Hardcopy mags. They
are more expensive: $1000? The SAM might have an aux relay output to
implement a thermostat system.
	If you really want thermostat control, I'm not sure. But the X10
BSR home control system (DAK had some) might do it. It has relays and
power switches.
