0E800 that would be nice indeed, but I don't think it makes much sense to develop a Flarum-focused analytics software when you can simply use a general one. GA and Piwik are already well integrated with the Flagrow Analytics extension.
If it's about tracking visitors who use blockers or don't have javascript enabled, an extension that uses the Piwik server-side logs feature would probably be a lot easier to develop than a whole custom solution...
