I ended up just using json+commando for my prototype[1]. I'm not going
to overengineer anything yet. If there's a way write plugins for the
other implementations I could start hacking away at a common control
subset, since I do eventually want an iOS app that controls all node
implementations. I will try to get something working across multiple
implementations before writing up a spec.
