[zeromq-dev] Cannot get epgm pubsub to work

To try out ZeroMQ, I've installed pyzmq and zeromq 2.2.0. When I run
the example publisher.py, I am able to see UDP packages via tcpdump,

$ python examples/pubsub/publisher.py "epgm://eth1;" 3 5

[root at vagrant-centos-5 ~]# tcpdump -i eth1
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes
20:30:10.144813 IP > UDP, length 36

However, the example subscribe never receives any messages:

$ python examples/pubsub/subscriber.py "epgm://eth1;" 1

any idea what can be causing this?
