Guy I know is a builder. Has a closet on the top floor of his house that opens into a crawlway [lighted with LED lamps] leading to each room on the top floor. There are 2 large pieces of PVC pipe with wiring running in and out. One is to the 1st floor room below and the other is to the 2d story room beneath. There is a set of 2 larger PVC pipes that lead to the basement and electrical switching and panels. He has a strand of fish tape [http://www.harborfreight.com/50-ft-fish-tape-38156.html] in each to facilitate pulling wires.
He said it doubled the cost of wiring the house, but it has future proofed any wiring or room access needs.
He is a guy with a lot of money and WAY too much time on his hands, but I thought it was cool. He shows it off at cocktail parties. 7,000 sq. ft. house, sold it for 4 times the cost to build it 6 years earlier.
