Correction: The AirPort Extreme card can't. The normal AirPort card
can. Most 3rd party USB/PCMCIA ones can on Macs with the supported
chipsets. And it's RFMon mode, not promiscuous mode. Promiscuous mode
is getting all the packets on a network. RFmon mode is getting all
the packets from every network.

The bad news it, its pretty trivial for anyone to do anything, no
matter what security you set. It used to take 100k packets or so
for them to be able to decrypt the WEP encoding but new software
can usually do it in a few seconds now.
MAC address restrictions are fine but if someone has their card in
promiscuous mode, they can see what MAC addresses are being allowed
'cos that part is sent in the clear, outside of any WEP
encryption. And then they just clone the address of someone who is
allowed.
Mac users are at a disadvantage for hacking into other peoples'
base stations, the Airport card cannot be put into a promiscous
mode (where it reads and records all traffic) unlike regular
cards. so if your neighbors are al Mac users, turn on MAC address
filtering and you are free from them, anyway :)
I use MAC address filtering, without WEP, and figure it's good
enough. If someone wanted in, or to snoop, they are in, I just
make it a little hard for regular folks and it's enough to keep
most out.
IMO the most important thing for you to do for real security is
make sure your base station has "remote administration" turned off;
so people on the wired internet cannot try and telnet into it (and
believe me, they will). Setting up MAC filtering or WEP is helpful
but not really that protective.
HTH.
