Re: proton - Kerberos support is in progress upstream [0],[1], but as you
point out it's not yet available.  That blocks kerberos support for the
amqp1.0 driver.

Once proton does release that, and the amqp1.0 driver adopts it, you'll be
able to migrate to the amqp1.0 driver and continue to work with the QPID
broker (as long as the version of the QPID broker supports AMQP 1.0).

That doesn't help you now, but it is something to plan for.
