Hm. I see I have some more coding to do then... :-)

I am pretty happy at the moment though. My code that generates all the
statistics for Taginfo (http://taginfo.openstreetmap.de) runs in about 2.5
hours for the whole planet, thats less than half the time it needed when
it was using the XML file format. PBF rocks!
