[44net] More fun with DNS

Just curious, has anyone played with the more oddball things that can be done using DNS servers? I'm aware that DNS requests can be used to tunnel traffic (often used to get around governmental censorship in some countries), and that E.164 can be used to route VoIP calls, but how about some REAL fringe stuff? I was just thinking that, we're ham radio guys, and we don't really have a standardized way to do something like call CQ and have keyboard-to-keyboard or voice chats! Maybe something can be done using DNS that hasn't really been done before. Anyone have ideas? Blaine, K1QV Sent from my iPhone
