There are two issues here:
- Is there an analytics package that's open source and as simple/powerful as Google Analytics?
And, secondly:
- Would it be possible to reverse engineer a free-software replacement of the infamous 'ga.js'? It seems to me that this is probably one of the most-executed non-free chunks of JavaScript in the world, and it would be interesting if we could reverse it and create a Free Software equivalent.
Or is that too neckbeardy? On one hand, it would only ever be used by the nerdiest of nerds, but on the other hand, it would at least make an interesting statement.

I've been using Piwik for a while and although the features are great, it's really slow. Otherwise, it's been a pretty suitable open source GA replacement.
Is it a host-your-own system, or do they have a hosted version as well?
I think someone might offer hosting, but it seems like most people self-host. It's all PHP/MySQL so it works on any webhost.
It is self hosted
Piwik is very nice.
