I can't belive no-one has mentioned PURE COPPER RG6 or RG11. For MY dream home, my coax will be nothing but pure copper. I use copper clad steel for all my installs, and it works just fine... but still, I'd go BIG BIG BIG for my own house. And at least one RG11 to each location is probably insanely useless, but that cable is so FREAKING HUGE, I GOTTA HAVE IT. And a wireless network won't ever be as secure as wired network. It's just the nature of the beast. Go with some good cat6.
