This has always been the methodology without native support, quite
frequently with TIBCO Rendezvous for example.  Common use case has been
basic in-band management and monitoring.

However I have seen both TIBCO and Reuters add "full priority support" to
their platforms via priority queue implementations on send and receive side
and both resulted in significant performance hit.

The TIBCO side is just over engineered and relies on pools of queues and
workers, presumably there must be a case for heavy Java workers to function
more elegantly.  Reuters side implements fair queuing on priority such that
higher priorities will never completely saturate event handling.  With
multiple ZeroMQ sockets you would naturally have to implement such features
oneself as required.
