Personally, I see a lot of parallels between this and the exchange of
email which is a relatively well-understood problem set(connections,
queuing, etc.)
As the number of registries and registrars scale, it might be much more
appropriate to have those registries PUSHing messages only to those
that have messages in the queue rather than having the registrars blindly
polling each registry on a timed interval.
As such, I definitely think PUSH should be present as an option.
