I've written a similar piece of code once for a company I worked
for which stored the historical information in a database so that
you could show to customers, after having taken over their DNS
services, that the quality of the data in DNS and their DNS service
had actually improved.

Running it against zones like eu.org gave enough different kind of
failures to make sure that running it on customers networks was a
piece of cake :-)
