Ashley, I'm still looking for a concrete use case. I understand in theory what you are suggesting. Without a use case I cannot begin to understand what it is that I cannot do without a dynamic collaboration. As yet I do not have an example. I have lots for choreographies but none for you area. We spent a long time in the WG doing requirements based on use cases. Not one use case was presented or harvested that sheds light on what you are suggesting. So a use case really really would be most helpful in elaborating what it really means in real terms as opposed to just a feeling or hypothesis. If you have a use case I'd love to see it.
