You say that, but I don't see anything in the draft supporting it.
That would imply that each caller is subscribing to a *different* 
resource. But the procedures for identifying the resource to subscribe 
to don't differ from caller to caller. So AFAICT all the callers end up 
subscribing to the *same* resource.

That is why Dale and I are trying to create a mechanism/rationale for 
why the subscribers don't all see the same results.

	Thanks,
