What kind of Django book would you like to see from O'Reilly?

I'd like to see more about using Django to build webapps with the Google App Engine.

I'd like a book that integrated google app engine with django covering file uplaods, http tools like beautiful soup and enterprise integration. I bought the book oreilly google app engine book but it's approach did not fully embrace django, that was a lost opportunity.

I think the following topics could be interesting:

- A new version of Django is about to be released. A book that covers the newest features.
- There are a lot of useful apps/addons/extensions (such as django-cms). A book could cover the most useful ones and how these can be used to build specialized websites.
- How to combine Django with Google App Engine by using django-nonrel. Or make it even broader by using django-nonrel with no-sql databases as mongodb, etc.
- A how to switch guide from other declining web-frameworks/web-languages to Django(and Python). See for example:

Head First Django

I've always found O'Reilly's 'Definitive Guide' and 'Cookbook' style texts to be the most useful. The 'Learning' books have been very helpful to me for getting started with a new topic as well.

I'd like to see a couple of Django books. One that covered the basics, and one that covered advanced topics and things like performance on AWS and Google App Engine.
