Fabrication question

[quinrou]

Hi,

I have been messing with the Fabrication utility and definitly considering it to use on my next project. But before I need to completely understand it so I was wondering if someone could explain the router defaultRouteAdress on the modules.
moduleLoader.router = applicationRouter;
moduleLoader.defaultRouteAddress = applicationAddress;
I guess these are used to setup the piping system in the background so I wondering what other option do we have here?

thanks
Seb
