Whoa.

I'd really like to see this (maybe I can finally crack my school's WEP!)

Unfortunately, DSLua doesn't have a function for all-wifi sniffing yet. However, you might wanna talk to Sypherce, I think he made a packet capturer... sypherce?

some useful information for ya

First find the connection .generate some traffic with it.listen on that network until you see ARP packets.Because you generate traffic most of the packets are ARP packets.From an ARP packet you know the first 16 bytes of cleartext so the 16 bytes of cipherstream.

all the network traffic must be written to the disk This will turn out in a tcpdump-ish file with all the collected data.now use the correct algorithm applied to it
In wep the first 3 bytes of the key packet are always know.the program must try to determine the other btes.If enough packets collect, most guessed is good.using aircrack,if between 40.000 and 85.000 packets collected, in 50% to 95% can be cracked the algorithm of the wep key
