Oh, hrm... It'd be better if we were using a released version of django-nose. Erik maintains django-nose. It's probably a good idea to push python 3 support in there. Having said that, I just remembered that "go through the django-nose python 3 support patches" is in my queue of things to do. :(

I don't think it should get added to requirements.txt since it's not something you need to have installed to use django-browserid. We should have a requirements-dev.txt file which has development-centric things in it.
