No. The concept (as seen from outside) have changed between version 1.0
With 1.0 there was a messaging deamon called zmq_server, the
applications connected to the deamon to find out where other
applications are located.
With 2.0 0MQ works mimics standard BSD sockets, i.e. it uses DNS to

PGM is a reliable multicast protocol. Maybe you don't need your data to
be transferred using IP multicast, however, there are several scenarios
where publishing large amounts of data to a lot of clients would
overload the network. In such cases, multicast saves the day.
PGM and PGM2 are different versions of the underlying PGM library
(OpenPGM). Next release of 0MQ will drop PGM1 and stick to PGM2.
