Seriously, it is a lot easier to run cat 6 around a house.
First off, you have to be living in KC. That means that you have a basement. That means that you can run cat 6 into the first floor trivially. The hard part is dealing with the upstairs.
Depending on the builder, you likely have a tunnel that goes from the basement to the attic, or you might have 1-2 2 or 3" conduits going from the basement up to the attic. You can simply run a single line up there and then put in place a switch, while you splay out to the various runs from the attic.
If you do not have the easy access, then hire somebody to run a cat 6 inside of a conduit from the basement to the attic on the outside of the house. Do it in a corner, next to a downspout, etc. Then paint the conduit.
Also do yourself a favor and run a line to the outside. Ideally, it will be trivial to disconnect (or more likely connect). I ran line up from the basement up to the dining area which the deck is outside of. Inside, I put this in a single gang box, with 2 quickports RJ-45s. The bottom one goes to the basement/network switch. The upper jack goes to an outside jack. When I want the outside, I simply plug in a small 4" connector. Otherwise, it leaves me an inside connection (useful for winter).
