Did you actually work seriously with / inside 0MQ? It's indeed an intuitive library, but it's far, far from perfect, thus why it has been rewritten countless times by Sustrik (crossroads), then by D'Amore (nanomsg). The state machine in 0MQ is a nightmare of maintenance and a constant source of tricky bugs. The overall "all sockets in one" design makes things such as reconnection and peer identification pretty much impossible. Don't get me wrong, there's a lot of good in 0MQ. But calling it a jewel that will be in use for decades is far from reality.
