I'm just going to mention that NATS can be used as a general purpose transport, with encryption and a surprisingly capable authentication and authorization system. It also supports federating into clusters and superclusters. NATS has also come a long way in the last several years, in case anyone is thinking of some experiences they had years ago when it didn't have all these features. The question would have to be "what does your idea/project offer that NATS doesn't already offer?" I have no affiliation with NATS, but I wish that people were paying more attention to it. It solves a lot of problems people have.
