The modularity and Pipeworks demos are deliberately not loading the modules for two reasons. First, their focus is on inter-core communications, and second, it would be cumbersome for the beginner to setup, since in the real world you'd have at least 3 projects per demo; one for module(s), one for common shared code and one for the sehll/main app.
