> trouble being a bridge interface,

This is due to MACs being used for associating with APs. Bridge interfaces usually require the interface to support "promiscuous mode" and (I think) most wifi drivers do that but getting the AP to recognize the fake MACs might be a problem. On a regular wired network, you don't (typically!)

(Typically, because you actually can do this. Fyodor's chapter in "Stealing the Network" talked about this. I don't have a copy, unfortunately.)
