I think that's the wrong approach. The only thing that really makes sense is to go wireless. Now today it would be very hard to make it work, but I wouldn't be surprised in 15-20 years if the various home appliance companies had gotten together and come up with a common approach to netowrking their systems together so that you put one device in your home to actually be wired (probably a combination NAT/router) that communicates with your various appliances. After all I'm not sure why you need to deliver the ultra high speeds that fiber could deliver to your refridgerator.
the problem with this is wireless is open and can be cracked (sniffed). no offense but i dont want some idiot to turn my internet stove on when im not home :P. Me personally would want internal wiring. Also i would want fiber for the lowest latency posible. if you are going to wire your house for broadband why not spend the extra money for fiber. (your house cost over 100 k already)
