Then you can let Erlang supervise a pool of nodejs VMs. If you want to be fancy, you can implement a ping/pong protocol for detecting when the nodejs system has gone off the deep end chasing down endless chains of callbacks. :)

This would be my approach as well. In addition one can define a simple framing format like {packet, 4} and then pass JSON structures to node.js, which it has an easy time working with. Alternatively, you could lean the other way and pass the Erlang term format directly and write a parser for it in node.js.
