Review result: Ready with Nits

I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review.  Document editors and WG chairs should treat these comments just like any other last call comments.

Document reviewed:  draft-ietf-tcpinc-tcpcrypt-07
Summary:

This document specifies tcpcrypt, a TCP encryption protocol designed for use in conjunction with the TCP Encryption Negotiation Option (TCP-ENO).  Tcpcrypt coexists with middleboxes by tolerating resegmentation, NATs, and other manipulations of the TCP header.  The protocol is self-contained and specifically tailored to TCP implementations, which often reside in kernels or other environments in which large external software dependencies can be undesirable. Because the size of TCP options is limited, the protocol requires one additional one-way message latency to perform key exchange before application data may be transmitted.  However, this cost can be avoided between two hosts that have recently established a previous tcpcrypt connection.

My overall view of the document is 'Ready' for publication.

One small comment is that there are some id-nits, please fix it in next version:

  -- Looks like a reference, but probably isn't: '0' on line 323

  == Missing Reference: 'RFC-TBD' is mentioned on line 932, but not defined

     Summary: 0 errors (**), 0 flaws (~~), 1 warning (==), 3 comments (--).
