Yes.  If we accept Don Box's definition, I find myself 
puzzled about service autonomy over shared resources if 
any.  If a service can't share a resource, it's a method 
with private data (even if the data is in a database and 
not an object).  So all I'm left with is the granularity 
difference and is that really a difference?

It seems to be a terminology designed to sell the 
implementation framework and hide the details: that is, 
like ecosystem diatribes, it's metaphorical.

And a fundamentally different level of communication
failure potential.

I guess, to some, these differences are not only
practical but also fundamental. I have seen a few
such disussions back in the CORBA days.

Makes sense.
