Agreed - as a secondary, the help is marginal.

I'm *sure* they provide delegation of subdomain, given the customers
that they have. AFAIK, UltraDNS is a professional *enterprise* DNS
hoster. But I can be wrong on that ;)

The more interesting question to ask is do they have an API for
dynamically updating the DNS records. (Maybe just dynamic-dns? If
security is configure dproperly, that should work, no?) If it's an API
we can use, then it can definitly still be a win.
