Doug,
You said that the IEEE 1588 committee failed to come up with a security
mechanism. However, it did come up with one in the form of a security
protocol annex. It is informative and experimental but it was overviewed
by NIST security experts. Consequently, I propose to re-word your
statement so that the existing security annex is credited somehow. I
also propose to start possible security work by seeing how far one can
go with the existing annex. You might include Ron Cohen as cc so he has
the option to comment.
Antti

	Comment on TICTOC problem statement:
draft-bryant-tictoc-probstat-02.txt
	 
	The need for precise time and frequency transfer in engineered
LANs is gernally met by IEEE 1588-2008.  Such networks include high
speed printing presses and other industrial automation applications,
power utility substation sync, etc.  However the 1588 committee failed
to come up with a security mechanism.  So secure time and frequency
transfer in engineered LANs could be one of the charters for TICTOC.
