Thanks.  Okay, then assuming you've installed ZEO from Zope software,  
if your third-party product includes conflict resolution by  
instantiating a class defined in the Zope product directory, then is  
it also safe to assume that this product resolution is still  
available to the ZEO server?  For example, if I have the following in  
MyProduct:

from BTrees import Length

class MyClass(...):
     _count = None

     def incrementCount(self):
         if self._count is None:
             self._count = Length.Length()
         self._count.change(1)

     def getCount(self):
         return self._count()

Then do I have to make MyProduct.MyClass available to ZEO or is it  
enough that BTrees.Length is available?
