I was just thinking about this script, it would be a nice addition to add click tracking to it. Where when someone clicks an outgoing link from your site, the script logs the click, and where you can view different traffic stats in the AdminCP.
OUT CLICKS:
25
http://www.google.com
12
http://www.yahoo.com
10
http://www.vbulletin.org
etc...
Possibly browser sniffing, resolution tracking etc...
Just an idea.
