Every bed room & living space has Cat5 run to it. I've got whole house audio set in the kitchen/living room on seperate controls. The master bath has it's own. Family room upstairs has one. So does the future deck area. I'll be going with a 6 zone controller and that leaves one more zone open for the workout room in the basment when I get around to it. I'll be buying a squeezebox or a Sono system hooked up to my Rhapsody account for music. Plus a receiver for FM access.
The vaccum system will use a couple different setups. Bathrooms, kitchen and laundry room have kick pans mounted in the base of the cabinets where you can sweep stuff into them. Main floor by the entry and the upstairs bath have a dual kickpan & hose outlet so you can vaccuum with the hose attachment. Have a couple other basic outlets that work with just the hose attachment. It'll all be routed to the garage where the canister will be mounted...eventually.
I HATE HATE HATE having dirty floors. My wife couldn't care less. She didn't want/feel the need for the system. I said f'it and put it in myself. We've got a dog that sheds like crazy and the hair being everyfreakingwhere just annoyed the hell out of me. Sweeping it up is a pain in the ass and the vaccum is a 45 pound brick named Kirby that is a different kind of a pain in the ass to drag around. Plus it sounds like a freaking turbine running. Having the motor out in the garage lets me run it at night after the kids are in bed without making too much noise.
That's freakin' awesome!
Definitely going to have to keep some of this in mind when we build our house..
