You'll probably be better off using a dummy or tun/tap interface for MoL,
and masqing out to the real world. The problem with the AirPort cards
(which is also a problem with the Lucent 802.11s, because it's
effectively the same card) is that it only responds to packets for the MAC
it knows. Since 802.11 expects ACKs to frames sent out over the air,
unlike physical Ethernet (send-and-forget), you'd have to be able to put
the AirPort card into BSS (base-station) mode to get that to work. (Also
why you need either an access point or special support to do bridging.)

I wouldn't be surprised if no one's gotten it to work. It's a limitation
of the 802.11 protocol more than anything (and partly of the drivers -
Lucent won't provide the info on how to put their cards into BSS mode
without a lot of green forked over first).
