I could well be missing something! I get that zeromq is not quite equivalent to rabbit or Google pubsub but you do presumably still want the same kinds of patterns: pubsub, queues and maybe a bit of routing? So it is an alternative to (eg) Google pubsub and I think can be compared with it. Is there any case where it would be used for a different /purpose/ than the others?
