Improve node.js setup documentation

I'm loving the node.js integration module and am already finding ways to integrate it in more creatively as the days go on. One thing I have noticed though: server.js must be within a drupal instance to work properly, therefore always combining your drupal instance with your server. I want to scale my application and have mysql and node.js running on their own server, and apache on another box running my drupal instance. I tried putting server.js on another box and it runs perfectly, until I try and hit it and authenticate.

Per my understanding, you authenticate to server.js with an MD5 hash of your session ID. For the server.js to receive /auth requests correctly, hook_menu has to be implemented to tell the server that something requesting /auth/[md5-hash]. From then it does a lookup on the session DB table to make sure you are legit. If server.js is running on another box somewhere though, this means that it needs to have a drupal database for it, plus the most up-to-date session information. The only way I can see around this is setting up master/slave mysql configuration for drupal, with the slave on the same box as server.js, then having a vanilla drupal instance with the node.js integration module installed and enabled so hook_menu is called correctly on your server when hitting /auth

Am I making this too complicated for myself? Is there an easier way to offload my server.js that comes with the module onto another box and still play nice with my authenticated users?
