A co-worker of mine was recently telling me of a tool he had seen
several years ago. A utility where you could upload a floor plan of
your building and specify where your access points are located. You
could then walk around your perimeter with a wireless client with an
agent on it that would allow you to marcate the physical boundries of
where you want the wireless signal to reach and it would reject
clients outside this range based on the signal.

Has anyone ever heard of anything remotely like this?
