If you do that, you need to make your framework depend on your app, which is
wrong.
Instead I would create a ERXFrameworkPrincipal to provide the app a unique
Pilot instance...
Less Woish, your framework could also have a IPilotProvider interface
implemented by Application classes and then you could do in your fwk :
((IPilotProvider)WOApplication.application()).pilot();
