Hey @petegehrman, interesting thoughts for sure! As @amackenzie mentioned we do have the concept of ActiveFlowIndication that allows a consumer to know the state of their flow.
Are you essentially thinking about using this as a mechanism for leader election across multiple apps? If so I’d suggest checking out what @GreenRover contributed to the SolaceCommunity. He created the Spring Solace Leader Election project which allows for leader election for spring integration using Solace exclusive queues :). He also took the time to create some great docs and covered a few use cases that the project might be useful.
