Yes. It's a different paradigm. ZeroMQ and Crossroads I/O deliberately separate the channel from the computation. That allows packages of messaging logic (so called messaging patterns) to be pre-implemented and available out of the box. These deal with complex and hard to get right issues like error handling, pushback and fairness. In Erlang you have to implement these by hand.
