	the diff is rather huge.  given (1) the amonut of diff, (2) future
	maintenance cost, (3) lack of maturity (we have been using it locally,
	however, we have some functionality lacking like address filters),
	(4) future incompatibility with BIND9 in usage (like command line
	options), and (5) possible additional bugs/remote hole comes with the
	diff (I don't believe there is, but we cannot rely upon ISC advisories
	for modified part), i do not really feel like bringing it in.

	I do hope we have IPv6 transport-ready name server,
	but I think there are too much issues with it.

	normally we have IPv4 infrastructure, and DNS name lookup can be done
	over IPv4 transport (IPv6-only environment is rather rare).  I think
	we can ask admins in IPv6-only environment to install BIND9.
