If the other guys are willing to help with a few bucks and the labor involved, why not wire up cat5 and go full tilt with it? Doesn't take a whole lot of effort, or cash for that matter.

Apols to Zen - I'm still wary of wireless, not to mention the speed difference (if there's still one - last I studied up you could get 10basex on wireless and 100basex on cat5)
