> There are many clients (C1-CN). Clients may be hosted on several
> machines. Every client generates a request, sends it and waits for a
> response. Responses are generated by workers (W1-WM), which are
> symmetrical (exactly the same - every worker can service any request).
> Workers as well may be hosted on several machines (different than
> clients' machines). It is assumed that workers can fail, so a failed (or
> timed out) request should be retried so that another worker picks it up
> and generates a response.
> The typical architecture would like this:
> C1 \ /W1
> C2 ---- queue --- W2
> .. ..
> CN / \WM
> Queue handles workers registration, load-balancing and retrying. What is

Have a look here:
You want basically the same thing, the only difference being that the
queue should be standalone application (zmq_queue) rather than
