i took a look at h1karis code, and what he does is very simple, he 
checks whether there are multiple keys around. The problem is that this 
is a heuristic method. Limitations are:
1. You cannot detect 40-bit networks, which have only one key (dont 
take this fore sure, but i ll take a look at the specifications when i 
am at home)
2. There might be WEP implementations which use the KeyID field and use 
more than 40-bit. (especially none standard implementations, such as 
lucent routers or so)

there is no method (i know of) to decide whether 40-bit or 104-bits are 
used based on a cryptanalysis or some other flaw.
i ll think about an implementation, depending on the truth of my first
