As the principal instigator of using use cases to think about 
the proposed TLS 1.3, I have been trying to come up with a small 
number of use cases that cover most of the application space. So 
far for TLS I have:

   HTTP -- the original SSL use case
   Email -- POP, SMTP, IMAP which are not well served by TLS authentication

   Are there any others that should be included?


I would like to have some for DTLS as well, DTLS applies 
cryptography to UDP. It seems that DNS might be a good 
candidate, but can encryption even help DNS privacy?

Cheers - Bill
