I have one of these dealy-bobs:

I leave the light switch on, and this thing turns on the light when it senses motion, and turns it off some time later. If I want to turn it off _now_, I can turn off the light switch. If I want to turn it on _now_ (and not have to wave my hands around), I can flip the light switch off and then on, which works the same as it detecting motion. And this is on a three-way circuit (ie, two light switches, one light).
This may not work for your situation, but it's been fairly reliable, and obviously, you can't beat the simplicity of the install.
