@Dan Rodgers - you are welcome to try 3rd party managers with Corona (Deadline, Pulze, others).
I would definitely advise you to contact their teams (Deadline, Pulze, or other manager of your choice) and ask about the specific limitations. I would also strongly suggest testing both Corona and the render manager extensively, because different users use different workflows, and it is impossible for us to verify whether all of those work correctly. We are fine with issuing free licenses of Corona for such tests.
