Thanks for your suggestion, but it's not worth the extra complexity at all. I've read something about interfaces, but my project will be a small/middle sized one, and using such a sophisticated tool it would be like using a cannon to shoot a sparrow (as we are used to say here in Italy). Anyway thanks again for your comments. Andrea -- http://mail.python.org/mailman/listinfo/python-list
