This will not be possible at the moment. The USRP can transmit 8MHz of 
complex bandwith over USB 2.0, and a WLAN-Channel has a bandwith of 
22MHz. You can sweep over the WLAN-Area and detect power to see if a 
range has traffic, but you won't be able to decode a lot.

See the archives of this list, it has been discusses a few time in the 
last year or so.
