I was just looking at Django REST apis last night but didn't find this one. This seems really similar to django-rest-interface, except for the oauth. Anybody know the potential upside/downside to this versus djang-rest-interface?
Piston doesn't tie you to a model (although it can), which is very important for any decent sized API. Exposing models is something you want half the time, but there's a lot more to it.
