I just wanted to address this particular point, again.

IMHO, any record that doesn't support a service selector isn't doing its 
job properly.

You _have_ to be able to say "if I want this service at this domain, I 
either prepend this prefix, or lookup this type", otherwise you're just 
forcing _all_ services to connect to the A and AAAA found there.

A and AAAA should be for connecting to the right _host_, once you've 
established from the _service_ which host that is.
