I think everyone has been treating Alpha and Bravo as the same entity.

Correct.

Cookies wouldn't be part of that. For a start "once a day" would have 
the cookies up to tens of thousands of packets out of date (assuming a 
packet every second for a client that joined just after the last 
NTPD-NTS sync).

Secondly NTPD doesn't need the cookies, all it needs to handle a cookie 
is the master key.

It is implied in the draft that a single NTS node may provide key 
exchange services for more than one NTPD server.
