AIUI, the purpose of Reloaded is to support lightweight runtimes for 
things like EJB3 standalone, right? If that's the case what you describe 
makes perfect sense to me.

The big concern would be that as you "grow incrementally" and add 
functionality you'll end up redoing work that's done in the AS, 
reinventing the wheel, etc. So in the future, don't do that! ;) What you 
described in your first post isn't that; you're reusing stuff.
