PC's upstairs, XBox is downstairs. Going to have to run about a 75 or 100' ethernet cable around the corner and down the stairs... OR take a flyer on setting up a wireless network in the townhome which may or may not work without the pricey XBL adapter. Considering that I'm only going to be living there another few months, after which I can set things up however the hell I like at the new house, I think I'd rather just suck it up, get some 'lectrical tape, and strap a cable to the stairs.
On the downside, it's 100' of cable for The Neko to chew upon. We'll see how it works out.
