No, I got that part, I was replying to someone earlier who asked about
logging unauthorized connections. 

I just assumed that people who were wardriving were collecting that
information for the purpose of using those APs. I know I did it when I
first moved downtown before I could get internet access hooked up and I
needed to ssh to work to fix something. The architecture firm next door
must have a cisco since it bleeds thru all the way to my front room. I
found it with netstumbler, then connected. I assumed this was generally
the case, to try to actually USE the APs. Otherwise it seems, well,
silly and academic and geeky. Which is fine. 

Love u guys. 

Chris

Christian,

Wardriving is completely passive radio reception. In
other words, wardriving is simply logging the
available wireless networks in a location with no
transmission back to those wifi networks; it does not
mean attaching to those networks. So, the AP won't see
wardrivers, hence their MAC, _unless_ they attempt to
connect to its network.

Attempting to connect to a network would entail
sending radio waves from your WIFI card back to the
AP, but all the wardriving apps I've seen
intentionally do not do that, in order to keep your
rig from being detected.

For example, <a
href="http://www.thinkgeek.com/computing/accessories/6f76/";>these</a>
devices do passive radio reception of the 2.4Ghz range
in order to detect WIFI networks in the area, but
without the automatic logging that a PC can do.

You could easily do the same with the right ham radio
equipment in your car, albeit a lot more expensively.

Passively receiving radio signals is not illegal, as
others have pointed out. Transmitting on frequencies
that you do not have authorization for _is_ illegal.

John
