Not to mention the high turn rate that some companies have, it is still possible for an
employee who was let go/quit to
still be active in said directory.  Also not to mention IF company "a" employees more then
a "handful" of people ya'd
need to take the search time into account.

Also how long would a person have to be working there before they're added to the
database?  There are a whole LOT of
variables to take into account.

Live Long and Prosper
