It's hard to tell just with that description. If you have to distinguish between a Product and a Service, specially if you have to do things with one that aren't done with the other (so they have a different set of methods), I'd say they should be different interfaces. Of course you may have several classes implementing the same interfaces. BTW, what do you use to define the interface? zope.inteface? another package? -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
