** Control over downloads

  Find the control point for m2 using maven-wagon. At this point, inject
  a offline status parameter which is used when retrieving the specific Wagon.

  If <<<offline == true>>>:

  * If the wagon is not bound to "file://", then ignore the request and print
    a debug message.

  * If the wagon is bound to "file://" then:

 * information among plugins, is this more like an extension point - do we need a sort of bus for
 * application data - do we need a dictionary for our applications like Apple does. We could easily
 * hook into this and this is the model we need to follow - how many of our REST services do not map
 * directory to a method in the application interface?
