 From what (little) I've understood from some recent conversations in 
dns-operations, the DNS folks may be having some "interesting" 
interactions between spoofed source IP addresses on queries, lack of 
pervasive BCP38, and open DNS servers that might benefit from being 
able to use TCP as a transport more efficiently than it can be today.
