Ted is suggesting that you could construct a URI that entirely
encapsulated a DNS request.  I'm not certain that that is possible,
but it would be one way of constructing a protocol.

For instance, a MX request might be formulated by sending a GET to
dns:IN:MX:time-traveler.org

(Personally, I'm inclined to drop IN from the protocol, but that's just me.)
