 >"None of the questions we got were ones we're willing to support."

 This is a statement about what Tor currently supports, not a policy
 statement.

 You're looking at dnsserv.c for information on adding new types, and
 that's a useful, but you'll also need to figure out a wire format for how
 to ask an exit node for a non-A/AAAA/PTR resolve, and how to get the reply
 back. (See dns.c for the exit-node side of DNS lookup.  See eventdns.c in
 tor or evdns.c in libevent for the DNS backend.)

 For a much better place to start work on these things, see the two mail
 threads starting on tor-dev from last January, "Tor and DNS", and
 "DNS/DNSSEC resolving in Tor (PoC implementation)."

 The "Tor and DNS" thread had a design proposal draft in it, and some
 discussion.  I don't recall the state of the proposal; it could probably
 use some tightening up and another glance.  That would be a good place to
 start.
