It's time that things like this, that don't take a lot to integrate properly, are included. This is part of the new standard in web development.
Thank you for your input! We will consider this functionality in upcoming releases if it will be popular.
Everyone, please continue voting for this feature if you consider it important.

Piwik definitely needs to be integrated into Plesk, but as a single installation. Basically, subscribers would be set up as users in Piwik from Plesk through it's API, the structure is all there. By not having not individual installations for each subscription (like I've seen done) you're significantly reducing the overhead required, and your performance will increase.
The structure is there in Piwik to pipe and/or read logs, so there's no need to worry about having to build anything into your client's websites, it's all done in the back-end without them needing to do anything.
This should be straight-forward to build into plesk, and in this day and age it's quickly becoming a requirement...the HTML-Style stats are becoming outdated.
Maybe when I get some time I'll look into building my own solution into Plesk for this, but at this point I just don't time to spare (probably a good thing).
Would really like to see Piwik included into Plesk...even as an optional component.
