As far as I understand, ZeroMQ does not require a broker to perform the communication between publishers and subscribers, I don't know how that is implemented (what do they connect to? how each client discovers each other?).
I already got MQTT running, It's not completely clear to me how the QoS setting works (atLeastOnce, exactlyOnce, atMostOnce), I don't remember using that setting in Java (it probably had a sensible default).
