Attached is a very stupid example, which should show what I mean: Here
various abstractions are layed out in a way, that they execute in order.
Only one connection is used for order forcing, but still many s~/r~ are
active, all properly ordered.
Real life examples may not be so easy to sort, of course.

Well, you could, but s~/r~ is much easier to use. Also
delread~/delwrite~ with a delay set to 0 won't have a delay of 0 in
feedback situations, so it may even be more confusing.

It will be in the LAC proceedings available on lac.linuxaudio.org soon.
