[openstack-dev] [all] QPID incompatible with python 3 and untested in gate -- what to do?

Just to be clear: you're asking specifically about the 0-10 based
impl_qpid.py driver, correct?   This is the driver that is used for
the "qpid://" transport (aka rpc_backend).

I ask because I'm maintaining the AMQP 1.0 driver (transport
"amqp://") that can also be used with qpidd.

However, the AMQP 1.0 driver isn't yet Python 3 compatible due to its
dependency on Proton, which has yet to be ported to python 3 - though
that's currently being worked on [1].

I'm planning on porting the AMQP 1.0 driver once the dependent
libraries are available.
