right now:
  127.0.0.1:53 or 127.0.0.1:953

I'd like to use Unix domain socket instead, although chroot(2)s make
that more difficult. Unix domain sockets would have 2^31 limit on packet
size, I think.

I think that with DNSSEC, that running a local caching resolver will
become more useful. (Sun has "nscd", for instance)

Right now, pretty much every application that does a lot of DNS has a
cache built in. (i.e. web browser). Many of these caches do not respect
TTL at all, and rather than upgrading the cache, it makes more sense to
centralize things.
