That's only helpful for keeping people off a wireless network, not for
keeping wireless off a wired one. Let's say someone has a laptop with
802.11b built-in-- containing and controlling the perimeter gets more
difficult as the hardware transmits over multiple mediums.

Let's say your administrators are worried about layoffs and want to leave
themselves a WAP-enabled backdoor into the company network, or the sales
person who's been logged into the hotel/airport's wireless network on the
road comes back into the office-

determine this- I'm just curious as to how others are approaching these
