Embedding SOA in Django Using Celery

I want to implement a web application with an SOA design. I am thinking about using celery in combination with Django for this. But I have a few questions:

• Is it right to implement SOA design for Django
• Assuming this is the way to do authentication within Django. In particular, I would like authentication to be separated using the producer and consumer patterns. That way, a REST api (or anything for that matter) can be used to create credentials for authentication, and a consumer (within Django) can be used to read and use credentials.

Again, should I do this with Celery in Django?
