Except that the statement 'you can be assured that the intruder is
within a 100 yards or so of the access point' is simply false.  With a
decent directional antenna and/or an amplifier in the right range, you
can access an 802.11b network from a much larger distance.  You can
easily get a kilometer or more of range using antennas built from junk
(old dish network dishes work great).

Direction finding is possible, assuming you are not in an area saturated
by wifi traffic, which would make it much harder.
