I thought OpenAMQ implements 0-9.

Interop with the Java client and server of Qpid's M1 release is working 
now. It required a few tweaks, which will be in the next RabbitMQ release.

Looks like OpenAMQ behaves the same as Qpid in this regard, so the hacks 
we put in place to work with the latter should also work for OpenAMQ.

We have hacked the PLAIN authentication to match Qpids. Our AMQPLAIN 
authentication is what the spec defines as PLAIN authentication.

Is OpenAMQ doing PLAIN authentication in conformance with the spec?

If so, the only way I can think of addressing the discrepancy at our end 
is to check what client is trying to connect to the RabbitMQ server and 
make PLAIN auth behave accordingly. Same in our client code. That's 
rather gross and brittle though.

Does anybody know how things are looking on the OpenAMQ <-> Qpid interop
