I'm going to go slightly OT here and say, if you have any trenches open (water, utilities, etc) extra pipe or plastic conduit is really inexpensive to drop in for future proofing. Every trench we dug for our house 20 years ago got extra, and over the years, I've used most of it for one thing or another.
And dang, while I did prewire the house with lots of extra TV, phone, and outlets, I didn't run any empty conduit between the attic and crawlspace. And the house was pre "popularized Internet" so I didn't run any Cat5. I had to run all that through the crawlspace.
