Node.js Brown Bag
This tutorial will be targeted toward OS X users since that seems the preference of KACE engineers, but there's no reason this couldn't be done on your favorite linux distro.
Easiest way: $ brew install node
This should install both node and the npm package manager. If you already have node installed thorugh some other method and you do NOT have npm installed, you can do the fancy install with `curl http://npmjs.org/install.sh | sh`.
