I really like this, I'm looking forward to digging through the source and finding out how folks set up their django apps.
One thing I tend to avoid, however (of course this is just my personal taste) is templates in each sub-app. I feel like at that point there are just too many nested directories. I'd rather have one global templates dir for the entire project.
However, sometimes you have so many cross-links between apps in Django projects that taking out a single app to use in another project basically breaks most of the functionality.
There are big pros and cons for doing it either way.
