It appears an interesting hack would be possible here, in the form of a
proxy that recognizes both DNS and SSH (which are both pretty easy to
recognize, IIRC), and proxies the connection to the proper daemon.
Of course, this is a cludge, too, but at least it's more elegant and not
as likely to break stuff. Someone might even have already written one,
but I think it's likely you'll have to do it yourself.
