If you're using 1.3, you can make the e-mail address the username, which will automatically require it to be unique.
I haven't used django-registration, but many others have, so maybe they'll be able to answer. On face-value, I'd say that your question is a bit off, though; django-registration doesn't replace the contrib.auth system. It just provides a way for you to create a user-friendly registration system for your users, but it still uses contrib.auth on the backend.
