Home Automation has grown leaps and bounds, but you'll have to pay to play. The current state of the art is "Crestron", but is definitely Audio/Video oriented, but will control things and automate yourhome as well. Price tag is near a quarter million for most high-end installs.
http://www.savantav.com/ is much cleaner, easier to use, updateable, and is chomping at Crestrons heels. Also very expensive in the hundreds of thousands, but they did just release a simple controller for only a few thousand. FYI: Savant is based on MacOSX.
