It appears to me that this Working Group's efforts in determining what 
is appropriate for NTPv5 would be helped by analysing where use cases 
like below are mapped to current/expected protocol functionality and 
capabilities across PTP, NTP, and Roughtime. I would be happy to be part 
of or potentially lead such a thing if people felt it was worth the effort.

Making a timing protocol that is robust and secure is not at all solved by PTP.  That is how NTPv5 can make the world better.
