I see what you mean and admit it has happened perhaps twice so far that the light went out when I needed it. But the times when walking in darkness at night or when coming home are much more often, so overall it has been a win. Not to mention saving electricity, as you never forget to turn off the lights.

Me too, which is why I used the Kinect, which detects presence without motion, even in the dark.

That's awesome, have you considered blogging about your setup?

I have indeed: http://blog.mikebourgeous.com/2011/03/08/home-automation-and...

Hope you find it informative :-)
