+-Load other zonefile (or zone data in general) formats?  The BIND syntax sucks, but I'm keeping it as the default, it's too widespread not to.  However, the zonefile scanner is mostly cleanly separated from the rest of the code, and it wouldn't be that hard to add support for more formats (djbdns? a SQL connection? in both cases, they could periodically update using the same switching mechanism as stat() watcher above...).
