Unfortunately, I've only ever had two cards to work with, so I don't
know how much card A1 might interfere with card A2 talking to card B.
My only experience so far is that the signal strength from A1 is enough
that A2 will likely not be able to hear anything else - a pathological
case of the "hidden transmitter" problem. I even tried putting a sheet
of copper (foil) between the two cards.
If you want to do an imperical test of the system under consideration, I
have two WaveLAN cards in two industrial PC boxen, all set up and ready
