I am currently working on a node.js documentation app similar to andnodejs. I really like andnodejs but the versions of node are not being updated with the app. But I figured why not just let the user choose which versions of node they would like to have installed. Nodoroid solves this problem by allowing the user to choose which version of the node documentation they have. It also supports having as many versions as you would like. The view of docs will be in a similar manner to andnodejs.
