I'm actually writing a dynamic importer.

Basically when the program starts it queries all the loaded modules for 
a certain package. It then stores the module and class information in a 
database and then when a certain view is called the specific data 
required is loaded by calling importlib.import_module('module.class'). 
This then populates the view with the required data.

Basically the idea is to be able to display any data required without 
having to tightly couple the view code to a specific model type.

Thanks for the help.
