No, my 60 Ghz. wireless graphics card link takes care of that :-) Also helps to cook meals.

I think you'll find that many "normal" remote controls, powered by AA or AAA cells, can work from the next room, using the 
"bounce" effect referred to above.

I just wanted to point out that blasters using the serial port as a power source have very limited output, there's just 
not that much power available.
