django-registration with Google App Engine Helper for Django

[johnP]

Has anyone been able to successfully integrate the django-registration
app: http://code.google.com/p/django-registration/

in conjunction with the Google App Engine Helper for Django app?
http://code.google.com/p/google-app-engine-django

I'm assuming that the main issue is replacing the contrib.auth import
paths - but it appears that many of the required imports do not have a
replacement provided within appengine_django.contrib.auth

So the questions are:

1. does django-registration work with Google App Engine?
2. does django-registration work with Google App Engine in
conjunction with Google App Engine Helper for Django app?
3. Can someone help describe what needs to be done?

or:

3. What is the recommended alternative?

Thanks much -
