Document: draft-ietf-stox-chat-10.txt Reviewer: Brian Carpenter Review Date: 2015-02-21 IETF LC End Date: 2015-03-02 IESG Telechat date: 2015-03-05 Summary: Ready -------- Comment: -------- This is a well-written document, even for one who knows nothing of XMPP or MSRP details. It strongly reminds me of the days when we had to build file transfer protocol gateways between FTP, FTAM and various proprietary protocols - the main problem was mapping non-congruent state machines into one another. The current draft has an amusing example: "idle" legitimately maps to "active". I expect that full deployment will reveal issues that haven't been noticed yet, so I also expect to see this document back for revisions in a few years.
