I have a django application that I\'d like to add some rest interfaces to. I\'ve seen http://code.google.com/p/django-rest-interface/ but it seems to be pretty simplistic.
I would look into using django-piston http://bitbucket.org/jespern/django-piston/wiki/Home application if security is your main concern.
I have used django-rest-interface in the past, its reliable and though simple can be quite powerful, however django-piston seems more flexible going forward.
