I think there's a critical issue buried in this dialog:
how many parties need to agree on how much detail
of a particular set of coordinated interactions?

It's like, how many parties need to agree on this contract?
Or, some variation on a need-to-know rule?

Or, to put it differently, consider a range of
configuration options from:
0. zero-config (something like Mark's models), to
2. pairwise external interaction agreements with
coordination as internal responsibilities, to
M. many-parties-agreeing-on-all-details-of-all-interactions
(is that the BPEL model?).

Which configuration options would be suited
to which situations?
