This is my first time posting here. The article is sponsored by Rackspace and I do not know any other companies which are using Rackspace and Node.js. I'm interested in this area of discussion and would like to know if anyone else is using the Rackspace cloud and Node.js. I'd also be interested in knowing other ways Node.js can be setup to work with Rackspace servers. Any additional information would be much appreciated, thank you.
