Check out this JSON<->Protobuf conversion package: https://github.com/turn/shapeshifter
Would be neat to have a Bijection that wrapped this.

Awesome. We have a json injection for thrift here that we could use as a model:

Should be fairly short. Want to take this one on?

I don't actually have a need for it right now but if I do, I will :)
