I’m currently running Piwik 1.1.1 on my web site, which uses WordPress 3.0.4 as a CMS.
Today I paid a number of visits to my site, just to feed Piwik with a few statistics. However I get the impression that outgoing links (i. e. links on my site leading to other web sites) are not tracked. As I understood piwik, it should be possible.
