Has anyone here made use of the XML statistics interface in BIND9, to get

Yes.
We have a system where local scripts on our machines can plugin to the
net-snmp daemon via "pass_persist" and export a table. I wrote a script
to present the XML stats to an SNMP table.
We basically graph, total, successful and failed queries; it's more just
to get an idea of load than anything.
I've had a few queries asking to see these scripts, so rather than reply
individually to them all, I'll re-post my reply here:

It's tied into our homegrown server monitoring and management platform;
I can't just extract it I'm afraid.
There are Perl and Python libraries which implement the difficult bits
of pass_persist helper scripts; e.g.
http://search.cpan.org/~nito/SNMP-MibProxy-1.0771/bin/mibProxy
http://search.cpan.org/~saper/SNMP-Extension-PassPersist-0.03/
http://github.com/nagius/snmp_passpersist
In essence, it's just a python script that reads the pass_persist
command from stdin, and looks the OIDs up in a dictionary; the
dictionary is cached and re-built when >30 seconds old by requesting the
XML.
