"JJ,
	This reflects my approach,  I feel we could easily enable a more
fully capable Multiparty Colab in the way you describe without having to
explain much more than the current BSI.
	The only issue I see is that we would want to allow a party to
be half way through a transaction with one party and initiate a
transaction with some one else."

Dale> Yes, this is definitely something we need to figure out how to
notate. Can we add another flow construct to represent this
type of dependency? We should definitely allow this one to nest!

JJ> I think I support this case (using onInitiation) 

	If by simply making the Multiparty and Binary different in only
the number of roles we can achieve this I feel we should go for it.

Dale> Definitely agree that we should view Multiparty and Binary as
specializations, differing in multiplicity of Roles mainly.

JJ> the real issue is the CPPA. Dale do you have an opinion on how the
CPPA will work in that case and how realistic it is to change it?
