Aye. In a perfect world I'd have gone CAT6 STP, but I'm way too tight. As long as it's quick enough to stream media I'll be happy.
You do find out a lot about how your house is built when you take up floorboards and get inside cavities (NJ). In my case, it's all held together with sealant and caulk. Also a big job turned into a bigger one when I found the floorboards in our attic are pretty much past it, so had to replace a load of those as I went on. Made the cabling easier though.
