Adding REST to Django
I'm thinking of falling back to simply
  writing view functions in Django that
  return JSON results.


Explicit
Portable to other frameworks
Doesn't require patching Django
I've got a Django application that works nicely.  I'm adding REST services.  I'm looking for some additional input on my REST strategy.  
Here are some examples of things I'm wringing my hands over.

Right now, I'm using the Django-REST API with a pile of patches.  
I'm thinking of falling back to simply writing view functions in Django that return JSON results.
I can also see filtering the REST requests in Apache and routing them to a separate, non-Django server instance.

Please nominate one approach per answer so we can vote them up or down.
