subscribers cannot send messages

[Removed-5an]

I would like to use axon in a configuration where everyone is a publisher as well as a subscriber (So everyone can message everyone, no round robin, no guaranteed delivery). I would use topics to distinguish relevant messages. How can I achieve this with axon? When I attempt to publish as a subscriber I receive the error message in the title of this issue.
