Hi Yeah I am not sure with the nature of guava eventbus. If its pub/sub based then yeah it could make sense to allow 2+ consumers on the same topic name.
For that to happen, the endpoint need to implement, then Camel knows its allowed http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/MultipleConsumersSupport.html I think it was Henryk or someone else from the community who created this component. He may be able to provide more information. Also feel free to figure this out as well. And if its possible, then we love contributions. http://camel.apache.org/contributing.html And patches is welcome and all that.
