As I understand it this is indeed one of the ways that Ubuntu sysadmins can
roughly determine the number of users. Of course this isnt perfect. There's
the problem that more than one person might use one computer, some people
cache their updates, and many requests will come through an ISP proxy and
will thus all come from the same/similar IP.
I understand they also use the time server requests that Ubuntu makes after
an install to determine rough number of users. Each machine (if net
connected) checks in with ntp.ubuntulinux.org to sync the time. Also
suceptable to error of course as with checking web requests.
Then there is the "popularity contest" package, which allows the ubuntu guys
to know what packages are being installed. Problem with this is that it's an
optional feature, so many people will not enable it.
I recently heard from a Canonical person that this whole subject of
measuring numbers of users is one that comes up frequently - especially
within marketing circles. It's very difficult to say what market penetration
you have when you really don't know. :)
