Home Automation

I'm not much of a home-wiring expert myself. However, when my parents 
built their most recent home a few years back, they had the builder 
install stiff, plastic conduit throughout the house. It all runs back to 
a box in the basement. This makes running any kind of cable easy. I 
wired them for Ethernet, and put their DSL modem and switch in the 
basement. It was great. They have 3 rooms wired now, and it was trivial 
to slip the cat-5e cable through the conduit, instead of laboriously 
fishing it through drywall and studs.

The cool part is that you could just as easily use it to run other 
cables. If you make the conduit wide enough, you could even run multiple 
cables in the same conduit (i.e., cable TV, cat-5e, fiber optic, 
closed-circuit security cameras, etc).

I highly recommend it.

DVI, S-Video and RCA and other connection technologies run multiple signals in the same wire and the interference degrades the signals.  This is especially true over longer cable lengths, like those you might find in a home theater room where cables typically are run the length of the room from the A/V equipment in the back of the room to the TV/Projector at the front of the room.

Install GigE capable wiring, it will work just fine for 10/100/1000, so you can scale it up in the future as GigE hardware and network equipment come down in price.  As for the wireless, you can add that anytime.  I personally hate the bandwidth restrictions of wireless, I prefer the higher bandwidth of wired.  Just give yourself both possibilities, so as your tastes change, so can your network.
