Ha. That'll teach me to answer tor-dev threads assuming nobody broke
the threading. :)

So Nick, are you thinking we want a way for exit relays to receive an
already-formatted dns query inside the Tor protocol, and get it onto
the network somehow heading towards their configured nameservers? Or
did you have something else in mind?

I wonder if we want a begin_dns relay command, sort of like the current
begin and begin_dir commands, and then just let them talk TCP to one of
our nameservers? Or is that too much like the previous hacks?
