Just to add to a11r's comment: - this is not a new Protocol Buffer implementation. It uses the existing Protocol Buffers implementation for serialization/deserialization. - this is actual implementation for the service declarations you could write in .proto files already (previously Protocol Buffers could only generate interface stubs, without implementation).
