That looks interesting - unfortunately I'm using MySQL and too 
familiar/happy with it at the moment to think about switching :). I'll 
have to look out for a MySQL version.

I'm logging to Cronolog which I think has similar performance advantages.

This is the kind of thing I want to do, but is there sufficient data in 
the Apache logs? I suppose you can use a custom log format to log the 
X-Track header, but then parsing it might be difficult.
