Has anybody played with the X10 controller stuff. I have been thinking
of that for our computer room but I am not sure if we would have problems.
The hardware is cheap and readly available and can be easly computer

usual industrial quailty. There is also an upper limit of 255 devices 
and some possible issues with external interferance.
