I’m curious… if my wireless network is bridged to my “wired” ethernet computers through my wireless router, why can’t my wire-bound Macs play to the AirPort Express in the living room as well? Sure, I can “share” my iTunes music to another Mac that does have an AirPort card in it, and play from there— but doesn’t that seem a little… inefficient?
