I think there is something but I'm not too sure, but I've seen them at my school's library because we have like 60 or 70 flat panel monitors all connected to one computer. They have one network wire coming into a box near each monitor, from that, it gives 2 USB ports, some ps/2 ports, a monitor out, and maybe one or two other things as well. They used a Citrix (spelled right?) neighborhood network software setup but I have no clue as to who makes those boxes. Maybe you can find it on the Citrix website. If you get that box and still want wireless, you could probably just get a wireless network card that can be connected straight through a standard network card.
