Well one issue would be taking over one of the scanner's MAC address and then
you get control. Also it does give you access to the network at Walmart. While I
think it would be best to implement a VPN under the WEP encryption I don't think
they do it. Also Cracking WEP keys (IIRC) is illegal, its getting access to data
that you don't have permission to access. That is the illegal part. I'm sure if
you went to Walmart and sat down with Kismet running they would have an issue
with that, I know I would.
