I would think it would be useful to have something exactly like a stream but that allowed as many iterators as you like but that a mutex prevented any two from consuming the same piece of information. So if a lot of agents had a handle to a stream, would they have to attach and detach iterators to use the stream in syncronized blocks? Keep in mind, If never made an agent. just speculating based on the reading and videos.
