I've been working on pushing the django-dynamo idea further. The project is still undocumented but you can read the code at https://github.com/charettes/django-mutant.
Actually FK and M2M fields (see contrib.related) also work and it's even possible to define wrapper for your own custom fields.
There's also support for model options such as unique_together and ordering plus Model bases so you can subclass model proxy, abstract or mixins.
I'm actually working on a not in-memory lock mechanism to make sure model definitions can be shared accross multiple django running instances while preventing them using obsolete definition.
The project is still very alpha but it's a cornerstone technology for one of my project so I'll have to take it to production ready. The big plan is supporting django-nonrel also so we can leverage the mongodb driver.
