I really don't see how hook is anything like Erlang. It just seems like a thin message queue on top of node.

hook.io sits on top of Node.js and deals with IO. How on earth does this relate to Nirvana's goal of having something like Node.js for Erlang?

That looks like an interesting thing, but it is a something for node.js, not a "node.js for erlang".

By which, I meant to say "platform for building server applications in javascript, backed by the power of the erlang OTP platform."

Node.js gives server side javascript a platform, that's great. What I'm working on is giving server side coffeescript and javascript access to the erlang platform (and some really great erlang technologies.)
