Espruino-red: running node-red nodes in Espruino

Looks great! I've been interested in this kind of thing for a while (I really like the dataflow idea when used in the right place). Node-red's something I was planning on doing stuff with on the Puck.js hub as well.

So at the moment, you have a bunch of yellow espruino nodes, and all of those nodes run on Espruino itself - connected via MQTT?

I don't know how possible it is, but did you consider having just Node-red -> Espruino and Espruino -> Node-red nodes? Then you could decide where the nodes ran based on which side of one of those nodes they were on... It might save you re-implementing a bunch of nodes, specifically for Espruino?
