Subject: Wi-fi. Approaching customers

Gregh,
IMO, you're covered legally. I know it sounds fishy to approach a
potential client already knowing they're insecure...but don't all of us to
that on a regular basis? I mean I will hit google with a vengence before I
go into the kick-off meeting...I want to know what I'm up against.
I would respectfully request some time from a technical manager to present
your findings (show a kismet/netstumbler scan) and explain the dangers
(not the solutions of course). Hopefully, this will rattle the manager
enough to get the word up to upper management, and if you've left some
marketing material for them to look at, they can contact you for your
services.

Good luck!
Wade
