Wiring a House While It's Still Being Built?

digitalamish asks: "Back in 2001 Slashdot had this Ask Slashdot about wiring a new house for networking. Some of the comments in that discussion talked about running fiber vs cat5e. It's more than two year later, I'm starting to build a house, and I'd like to update this topic. So, what's the current state of people's thinking. Is good old Cat-5e still good enough, is fiber a better option? What about other options like Cat-6? Or with the state of wireless, is wiring a house even worth it any more?"
