Piwik and FireStats

Installed Piwik and FireStats, both are runing on PHP and MySQL for web analytics.

Piwik uses Javascript, FireStats has a "middleware" to deal with Django.

Piwik has nice charting, as it aims to be open sourced Google Analytics, however it seems still not has the desperately needed excluding IP feature implemented.

FireStats has IP exclusion.

Piwik is open source, FireStats is not free for commercial use.
