[Twisted-Python] Newbie question: How to reference the "__main__"

Just use a singleton design for your Configuration class

class Configuration:
	class __impl:
		def __init__(self):
			# do your stuff here
                        #
	

    	__instance = __impl()

    	def __getattr__(self,attr):
     	   return getattr(self.__instance,attr)

    	def __setattr__(self,attr,value):
     	   return setattr(self.__instance, attr, value)
	

whenever you instanciate Configuration the inner __impl instance will always 
be the same. Maybe I missed something above - just look up the singleton 
design in the python cookbook (activestate.com)

Hope that helps
