ah, but the pipe is the transport. 
try:  ls | zcat | sort

	Yep, that's a toughie.  I'm not going there. 8-)

	Sort like "ls" and "sort"; no coupling at all, except that both are
	developed to an abstraction with a single uniform semantic which permits
	state to be transferred from one to the other, ala "ls | sort".  That's
	exactly the kind of loose coupling that I want Web services/SOA to have.
	But it's not what we've got.  It *requires* a constrained interface,
	because that is how the common abstraction is reified.  In Unix, that
	abstraction is the "pipe".  In Linda, it's the "space".  In the Web it's
	the "resource".  In email, it's the "mailbox".  SOA needs one of those.
