Hell, Peter.

It's easy (like most things in Python!).  Just define your class global
variable, using the class name to the left of a dot.  For example:

        >>> class Factory:
        ...	def printer(self):
        ...		print self.value
        ... 
        >>> a = Factory()
        >>> b = Factory()
        >>> Factory.value = 3.1415926
        >>> a.printer()
        3.1415926
        >>> b.printer()
        3.1415926
