With pubsub it works exactly the same way in a multi-module app as it 
does with a single module app.  You simply have one part of the 
application that subscribes to receive messages of certain topics, and 
another part of the application that publishes messages with those 
topics.  It doesn't matter if they are in the same module or even the 
same class, or not.
