Hi again, 1. Are there any parts of the ZPattern that demands TTW developement? After reading alote of intresting discussions I find that there is alote of talk about ZClasses, but as I understand it they can be Python subclasses of ZPattern base classes as well? 2. If I want to write a default implementation for an application storing data in a SQL database could I just subclass DataPlugins and add my SQL-methods in that class?
