Hi Russ,

Thanks for the advance notice.  As you write your Internet-Draft, can I
encourage you to write a comparison (advantages, disadvantages) between
CCM and the less fancy encrypt-then-authenticate generic composition of
CBC mode encryption and CBC-MAC authentication (suitably modified to be
secure for variable-length messages)?
