The wording of the required broker setup to run the examples is a bit misleading.
The qpid-proton/python/examples/README.txt states that the examples requires a broker accepting links to and from a node named 'examples'.
Most (though not all) of the current examples require a broker or similar intermediary that supports the AMQP 1.0 protocol, allows anonymous connections and accepts links to and from a node named 'examples'.
If for example someone setup Qpid Broker-J and create a virtualhostnode 'examples' the examples don't run. Rather a queue with the name 'examples' is required.
