The problem is the wireless end. See the FAQ and mailing list archive for
some background info. Basically, most wireless cards don't want to be used
in this fashion.

It vanishes from the network between the moment that you enslave ethX to
the bridge and the moment you re-assign the IP address to brX.

A bridge is transparent to the network. It connects to one subnet, and
has only one 'presence' on that subnet.

This doesn't work. A bridge is like a hub/switch.
