Where I work we often use the boot disk's UUID or the first network card's MAC address to identify a machine. That's not perfect, they can be played with too, but they are typically more stable than a machine's IP address.
Is the data anonymized before it is sent? Or only once it arrives on the server? Is it sent over a secure connection? Just some questions that come to mind, I'll try to look at the code later.

So it runs /etc/cron.weekly/pkgstats. Does that mean it runs Sunday at 00:00? What happens if my machine is switched off then (laptop)?
@schultzter you miss some important points which was mentioned by @Pierre
Not at all.
1) I don't want track individual users for privacy reasons.
2) Everything that is sent by pkgstats can easily manipulated by the user without us noticing. So any idea based on sending data is flawed.
3) The IP hash is only used to prevent too easy flooding; not to track users or make the stats any more accurate.
4) There is no way to get exact values, but over time if more and more people use pkgstats some single variations (e.g. when someone sends garbage) wont matter.
