Dave ...

I've been running a sort of "glorious experiment" within net 15 (HP)
to try and determine how widespread the use of NTP really is.  The
results have been a little surprising.  While I expected to see on
the order of 2500 to 3000 hosts using ntp,  what I found was a varying 
number that seems to run from 500 to 750 on the outside :-(.  Its kind of
a top heavy tree with as many as 30 strata 2's .... more data here
as I determine it.  The reason for this project is that we are working 
on a more optimal internal structure.

Tools used include a mongo perl script and some mod'd binaries of ntp,
xntpdc, and ntpq.
