Joel,

I apologize but somehow I missed your message.

Please see comments inline.

I think an important use case is to allow for 3rd parties to see an
association involving 2 parties that may have been created
by a 3rd party, but only if the 2 parties involved in teh association agree
with the association's implications.

I think Nikola's point is that confirming associations may become a
bottleneck or burden on parties. This may well be true
but it remains to be seen through the eyes of experience. I can see a future
enhancement like:

-each User instance specifies User preferences such as "I allow associations
to my objects to not require confirmation". I can also see future
enahncements

-A User grants another User privileges to create associations to their
objects without needing confirmation

-An access control policy on an object which says anyone can freely create
association to it without requiring confirmation

However the base or default rule should err on the side of conservativeness
and say unless explicitly conformed an extramural association will not be
publically visible.
