thanks fawcett! with a name like that... "Johnny Cache is a caching framework for django applications. It works with the django caching abstraction, but was developed specifically with the use of memcached in mind. Its main feature is a patch on Django’s ORM that automatically caches all reads in a consistent manner."
"django_cas is a CAS 1.0 and CAS 2.0 authentication backend for Django. It allows you to use Django's built-in authentication mechanisms and User model while adding support for CAS.
It also includes a middleware that intercepts calls to the original login and logout pages and forwards them to the CASified versions, and adds CAS support to the admin interface."
