First of all it is not developed by Beyond-Security.

LEAP is a Lightweight Extensible Authentication Protocol from CISCO.
It uses challange response, like mschap. Got the same bugs, nothing to
do with Radius or WEP. Get the details on sourceforge.

Forget the 802.11b/g does not use frequency hopping. The amount of time 
to crack is only
a few seconds, the major time factor is having the right wordlist to 
prehash from. If you dont
have the password in your list, only bruteforce can help you, so then 
it depends on the complexity and the length.

Nothing to do with SAM etc, because it sniffs challange and response 
and then offline crack it.
