I have automated my home using Insteon from SmartHome and using Indigo running on a Mac Mini. Been a great experience! I can control the lights, A/C and cameras from anywhere which has been made even better by Indigo releasing an iPhone client so I have even better control of all the elements. Pretty sweet to have a theatre mode on my Harmony remote that dims the lights, and plays movies off my AppleTv all in one button press, and when I pause the movie the lights slowly come up so you can find your way to the bathroom
