the M3 REAL just released new firmware that rocks. you can get whatever you want from the transmission of a DS with a laptop. They simply use 802.11 and support only WEP. so you could arpspoof, fragroute, dnsspoof, etc, and just sit there in real time. Twas one of the first things I tried during my WiFu exploration. you can also Deauthenticate a person with aireplay-ng if they are winning at mario Kart and you can beat them.
