Great article. ZeroMQ had a "smell" that I couldn't put my finger and thing article kind of nailed it. In retrospect I guess the smell is that it is tightly couples both sides of the network to make performance claims. It sacrifices robustness for performance. I guess that it was developed for financial trading applications. Maybe it will work fine for those -- you have a few machines and high network connectivity between them. But people started doing "data center" stuff with 0MQ. Then you have geographical separation, and WAN latency and reliability.
