Just watched the endpoints demo in google I/O 2012 (http://www.youtube.com/watch?v=NU_wNR_UUn4 and also http://endpoints-trusted-tester.appspot.com/).
If I understood correctly this replaces the functionality offered by ProtoRPC API, as well as providing an automatic way to prepare the client side API endpoint.
Since this can affect my decision of using ProtoRPC in a future project, does anybody knows whether Endpoints is going to replace ProtoRPC or not?
Cheers
The Python implementation of Endpoints is built on ProtoRPC. Rather than thinking of it as a replacement, I would consider it a supplement.
