First things first: a very good job, integration wise, so far.
What is your estimate on when we can try out django-mongosession? Are you short on committers/contributers?
For a current project of mine, I require a working document form and a working backend admin site and standard user management including standard authentication.
If you need help, I would be glad to contribute to your project.
Always looking for help - there is a sample app that I use for testing.
Regardings release timetable - I need to update to support django 1.5 and write the documentation. Also, I will have to write test cases - probably opting for functional tests using the sample app
