Hi, I do not support adopting all four drafts, I believe that we should either integrate them into a new revision of NTP ("NTPv5") or fix them problems/issues they address in that new "NTPv5" RFC. Most of the issues addressed by those drafts can be easily solved by changing/expanding the NTP packet format for "NTPv5". The "REFID" draft would be obsolete if an NTPv5 packet header for a server mode packet by definition includes a "MY_ID" field. The "MAC/last extension field" draft would be obsolete if we define that NTPv5 does only support Extension Fields as allowed additional data and a MAC in v5 is always transported inside an extension field (the "MAC-EF" approach as described in the draft, for example). The "I-DO extension field" draft would be something I would integrate into a "NTPv5" RFC as a mandatory requirement for NTP servers. The "Extended Information Extension Field" draft would be obsolete if we introduce either additional packet header fields in v5 or just defined a new EF for information that we think should be available from the server. That EF could be sent or not, based on whether the client wants it or not (indicated by an EF sent by that client in its request, for example).
