I'm the current maintainer of ttdnsd and I fully support using something
that isn't such a hack.
I know that Paul Wouters and another unbound developer hacked together a
udp/tcp listener that only made outbound TCP connections. I think I made
some notes in the ttdnsd git repo at one point.
There was a patch that needed to be applied to unbound but I believe it
is now merged. If that is the case, I think that unbound and either
TransPort + iptables, socat, torsocks and unbound would be the best path

That sounds interesting.

I think this doesn't scale very well but it's never the less quite
interesting as well!
All the best,
