I haven't understood everything, but I have next question for You.

class WithinObject1:
	def __init__(self):

	def methodW1(self):
		print 'Hello from WittinObject1 class '

class WithinObject2:
	def __init__(self):

	def methodW2(self):
		print 'Hello from WittinObject2 class '

class Listener:
	def __init__(self):
		self.sevice = ObjectService()
		wobj1 = WithinObject1()
		wobj2 = WithinObject2()

What would you do in that case? Inherit from ObjectService is impossible  
because you will create two services with the same name. Methods methodW1  
and methodW2 have to be in the same interface.
