Oh, come on.  That's not a bad pun.  Bad puns are REAL groaners.

I didn't realize that WEP had become as vulnerable as it seems to be.  I 
was also going on the assumption that the little traffic I generate 
would make WEP key recovery difficult.  It seems that current cracking 
tools are able elicit traffic from an AP without connecting such that 
the key can be recovered without seeing any traffic that I actually 
generate.  I guess the behavior isn't that surprising given how easily 
wireless stuff connects.

Looks like I need to bump the priority on implementing WPA.

Cheers,
Dave
