Full Disclosure: I'm the lead node.js developer advocate for Rackspace

As it turns out, we're announcing our node.js SDK plans (with support) today:

As a side note, we have open sourced many projects in Node:

* https://github.com/racker/node-elementtree

* https://github.com/racker/node-cassandra-client

* https://github.com/racker/node-zookeeper-client

* https://github.com/cloudkick/whiskey

We plan to release an official node.js SDK soon. I don't have a specific date, but it should be relatively soon.

The article says node.js support is on the way.
