Just finished a fairly large pilot test with grpc. Summary: it's not production ready. It seems to be still moving rapidly and bugs pop up. I'd recommend holding back for awhile longer. Also, instagram heavily relies on JS. There are not any protobuf parsers in js that perform anywhere near that of native json. The most feature complete implementation is two orders of magnitude slower. Using the C++ bindings is faster, but is more difficult to fit into a typical build, can't work in a browser, and still an order of magnitude slower. It's definitely something to keep an eye on, but, IMHO, not quite ready for something large scale.
