Darien, according to 802.11, if you set the SSID to a zero-length field, ie the NULL string "", the station will enter passive scanning mode, and will associate with the first SSID contained in an 802.11 broadcast beacon. Setting the SSID to "ANY" is treated specially by the driver and actually becomes the zero-lenght string "". What you want to do is decoupled from SMN or any other scanner. With the aironet card, you simply type ifconfig an0 ssid - and it will magically associate. This will work only if the AP is set to broadcast the SSID, which is not a very good idea from a security point of view, especially if you don't use WEP (which itself is broken but a lot better than nothing).
