I've got most of the ethernet running through my house. I've got two rooms that each have four jacks in them. Four in my entertainment room (need something to plug the Playstation into!), four in the livingroom, and the third and final room to get ethernet will be my bedroom. It will be getting four jacks as well, although I'm going to have to run the Ethernet under my carpet which is going to be a bit of a pain. It's that or tear holes into my walls so that I can drill holes into some "fire breaks" or something like that running between the studs in the walls. They're quite annoying, having blocked my wire running up into the attic.
