RE: Some proposed definitions of "web service" based on the call toda y

All the choices you list are based on the premise "our definition of Web Services is different and presumeably broader than the set of constraints/principles/defnitions defined by our architecture". From that premise you start mentioning two "things" in all your choices. 

I am not at all convinced that we need to talk about two things. In fact, my point yesterday was that we only need to talk about one thing.
