When I've done it, I've made the register assertion in the App  
Delegate's awakeFromNib():


class DropView(NibClassBuilder.AutoBaseClass):
     # react to drops here


class DNDAppDelegate(NibClassBuilder.AutoBaseClass):
     """
     The controller for Drag & Drop
     """

     def awakeFromNib(self):
         # 'drop_zone' is a connection in IB from our AppDelegate to  
the DropView
         self.drop_zone.registerForDraggedTypes_ 
([NSFilenamesPboardType])
