It's like Mato says: using a dynamic name service, a service can bind
to "random port", then publish its presence to the name service, which
clients then use to look up the address and port of the service.

There's a pretty complete implementation of a name service
architecture (missing only the actual payloads) in the Guide Clone
examples.

Mato: IMO this should be done in language bindings, not libzmq. I
added the concept to http://www.zeromq.org/topics:binding-abstractions
some time ago.
