ZeroMQ is a library that implements an application layer network protocol. Hatchet is a distributed job server with durability and transaction semantics. Two completely different things at very different levels of the stack. ZeroMQ supports fan-out messaging and other messaging patterns that could maybe be used as part of a job server, but it doesn't have anything to say about durability, retries, or other concerns that job servers take care of, much less a user interface.
