Renat, Alternately, what do you think if mistral just post the events to given exchange(s) on the same transport backend and let the subscribers decide how to consume the events (i.e post to webhook, etc.) from these exchanges? This will simplify implementation somewhat. The engine can just take care of publishing the events to the exchanges and call it done.
