The paper remains abstract (i.e. vague) about users.

But I do identify three 'use-profiles' in 4.1, at:

Agreed that, to the extent that a service-provider (operating on the 
right-hand side of the diagram) itself uses services that are 
provided by a cloud service-provider, then, to that extent, they are 
also users (on the left-hand side of the diagram).

Self-referential / nested / recursive, call it what you will.

Agreed.  But note that this includes:
2bi  organisations (nomatter what size they are)
2bii human beans

Agreed.  I don't treat them separately though.  I think the comments 
I'm making apply to them in much the same way as to the others.  (If 
I go deeper than the current 3,000-word diatribe, differences would 
start emerging).
