Note that CLIENT and COLLECTOR are redundant as CLIENT is just a worker 
that happens not to receive any messages and COLLECTOR is just a worker 
that happens not to send any messages.

Which leaves us with a nice model with a single socket type... 
Unfortunately, it cannot be implemented. The problem is that WORKER 
socket has to be connected to two different kind of peers (upstream 
peers and downstream peers). zmq_connect() and zmq_bind() don't provide 
a way to distinguish between the two.
