Well, I don't know about most people, but I run OpenDNSSEC with (as of
right now) 2350 zones, and 5280 keys (with rollovers going on and all).

The SQLite backend was nice to begin with, but it is not workable for
large zone numbers.

I have not yet migrated from 1.4 because, well, ENOTIME, but it was on
my TODO for before the summer, I'd rather be sure quite it is going to
work :-)
