If all goes well, this summer I'll be building a new house. I've owned a few houses before, some of them built in the 1920s and 30s, and full of all the charm and quirks of an old house, and a couple that were pretty new, with the lack of craftsmanship and imagination that's typical in most new construction in the USA today. But this time I'm building a custom home, just to my specifications, so I can have whatever features I want, limited only by my imagination (and budget). I'd like to integrate some home automation features into the house, and include wiring for future expansion.
You are definitely on the right track! As a tech rep for one of the companies you listed from the show you attended, I would advise you that wireless is a very effective enhancement to a hard wired network infrastructure. I would also highly recommend seeking the help of a low voltage systems integration company to help you get what you want from your new home. In my experience, there are very few electricians with the ability to provide you with the level of integration you are looking for.
