It's very well possible. You create a new distribution called for example "Interface". Now you can write: import interface import zope.interface class IFoo(interface.Interface): pass class IBar(zope.interface.Interface): pass Depending on what "kind" of interface you have the semantics of calling these are different. Not that I'm proposing to do this, as it leads to a pretty horrible mess, but it's possible. We are just now getting rid of the old Zope2 Interface package and its usage in Plone land, which has the same kind of incompatibility problem. I expect that old version of interfaces is still going to be with us for a number of years. So experience shows that something so central, even if not used for many important things, has a much much longer lifetime than you'd expect.
