Yes, we're getting Monogram, I believe. And yes, Cat-6 everywhere!
Not a huge distributed audio/video guy, but the house is structured wired in Cat 6 with a 1Gbit hub. The CEO picked out all the appliances, the lighting (the price of which almost made me faint!!), the tiles, the granite... well, everything, really.
The ONLY thing I asked for was the coffee system and the structured wiring. Everything else I left it up to her.
