Keith,
My template, which I will teaching on this fall, uses the MVP development pattern for modules. I have some extra folders - Presenters, Models, and Views. The way I do DAL2 currently is place my "Repository" classes for the DAL2 controllers in the Components folder and the DAL2 entity classes in the Models folder because these are typically used as the model data in our MVP pattern.
When I have done enterprise development where I pull the entire data layer into its own project (class library) to be shared by multiple modules, the module layout changes quite a bit.
