I am working on a GAE application that will use its own registration module. It works using AJAX, can create new users in the database, send codes to check new users and restore existing users via e-mail. I have almost finished working with this module, and I am sure that it does not take a lot of time to configure using Django models to work with the database. The important thing you can take from there is the concept of registration / verification / recovery processes. Please feel free to clone the module from here and participate in its development. You can also ping me, if you have any questions, I will be happy to help! Thanks.
