Re: My addition will take almost 2 miles of Cat 6 I find it interesting that people don't understand the reason for multiple connections in a room (not that the OP hasn't gone to an extreme). I have rent houses which have two or three Cat5 in some bedrooms. Not all rooms have only one way to arrange the furniture. Much easier to put in a few extra so you can put the bed where ever you want instead of "well, the bed has to be here because the TV can only be over there". The time to do it is when the walls are open. The price of copper is the cheap part of the process.
