Thanks for all the info, guys.

As I was piecing together a list of modules to buy, it occurred to me that the dimmer switches probably won't work well with compact fluorescent bulbs. I am trying to use as many CFLs as possible in my house to save energy, and a quick read of the SmartHome forums suggests dimmable CFLs are hard to find, expensive, and don't actually work all that well. Looks like I'll have to use incandescents on any lights I want to dim.

That automatic blind idea sounds great. What blind motors did you use?
