I agree with that. I can't see more scenarios for other kind of
applications now but this two cover most cases.
For a content management system for example, things are done per
folder and the constraints are done per folder as well. Think on how
would you implement a plone site with all the contained types,
On the other hand, for a simple aplication that excutes a given task,
say a flicker search or a web app to manage an email system for
example, you can have a grok.ModelApplication as a site with a site
manager container in case you want to create views to control the app.
Personally I see the last as a utility app that executes a given task
tho....not a huge app.
