I'm currently looking at enabling the Bunny Ruby AMQP client to use
either 0-8 or 0-9-1 depending on a user supplied option. I've started
to do some interop testing against Qpid 0.5 with a view to tackling
OpenAMQ later. I would be happy to help out if I can.

Is there a version of RabbitMQ that I can test 0-9-1 functionality
against. I have v1.6.0, can I use that? I've tried but can't get a
connection/channel going. Not sure if I'm sending the correct
information to initiate a communication session.

Chris
