Subject: [tcpinc] new revision of tcpcrypt draft

we've posted a new revision of tcpcrypt:

  https://tools.ietf.org/html/draft-bittau-tcpinc-tcpcrypt-04

it takes advantage of the negotiation mechanisms of
TCP-ENO[1], and is half the length of our previous drafts.

because ENO itself provides the means for negotiating among
future versions of a TCPINC protocol, we've streamlined
tcpcrypt in the interest of easing analysis and
implementation.  for example, RSA has been removed as a
key-exchange method, leaving a choice among three,
uniformly-handled schemes based on ECDH ciphers.

(one of these, Curve25519, is currently specified with the
help of a normative reference to an I-D.  this key-exchange
option could simply be removed if no RFC is published in
time.)
