unbound via dnssec-trigger does this. The problem here is that it
still does 1 query/answer per TCP connection. That has to be fixed,
and we should use a dnssec chains format for it. Ideally, I'd like
to say something like "give me the proof from .ca to IN A www.nohats.ca,
and receive one blob back.

I haven't encountered a hotspot that, after authentication, breaks port
80. This setup will work tremendously well. But currently, using port
just causes timeouts.
