A much simpler question. The answer is "yes" with some caveats.
It assumes that the AP is transmitting a beacon (which a public system
will) and no WEP. If this is the case, it should "just work".
You can probably just (as root) issue 'dhclient wi0' and it should do
the trick. You probably want to be sure that your /etc/start_if.wi0 sets
the ssid to "" and wepmode to "off".
