ZeroMQ output. see www.zeromq.org for more info
From the ZeroMQ manpage 'zmq':
The 0MQ lightweight messaging kernel is a library which extends the standard
socket interfaces with features traditionally provided by specialised
messaging middleware products. 0MQ sockets provide an abstraction of
asynchronous message queues, multiple messaging patterns, message filtering
(subscriptions), seamless access to multiple transport protocols and more.
