Hi Heiko, Doug,

Thanks for putting this draft together. I believe it can be very useful to the industry.

After going over the updated draft I have a single comment:
Please consider allowing unicast negotiation. The reason I am raising this is that multi-path PTP (draft-shpiner-multi-path-synchronization) would require Sync messages to be sent as unicast, and hence require unicast negotiation. I believe MPPTP can be useful in the context of this profile, allowing both redundancy and higher accuracy in some scenarios. Will appreciate if you can give this some thought.

Thanks,
Tal.
