Looks interesting. But shouldn't a library like celery work outside the context of a web framework? I don't see a reason to call this a distributed task queue 'for Django' specifically, except for the dependencies on Django's ORM and settings definitions. Swapping out Django's ORM with SQLAlchemy (or DB-API) would make this project much more useful.
See pp (http://www.parallelpython.com/) for something similar, without the django dependency. More parallel processing goodies at http://wiki.python.org/moin/ParallelProcessing.
