Massad Ayoob gives a lecture on this topic. He has his place rigged, and recommends that others rig their places, so that he has a master lighting panel in the bedroom. He can turn on lights at will, without physically entering a room, while he keeps his defensive area dark.
I have X10 switches in my house and can turn on the living room, front and back lights at the touch of a button. Hallway stays dark and everything else is lit up. You can mount stick on wall switches anywhere you want. Very handy.
