Node.Js in Erlang style?

Я полный нуб, когда дело касается как Node.Js, так и Erlang. But wouldn't it be possible to build a Node.js app that emulates Erlang behavior?

e.g. you pass json messages across an distributed node.js server park and even pass new code to those servers w/o going offline, just like erlang.

If you have a message handler callback that is activated when a message is received, then this message handler could check if the message is a code update message and thus replace itself(the current handler) with the new code.

So it should be possible to have Node.Js servers with no downtime for code updates w/o too much fuss, right?
