Etherpad Lite and Drupal

I'm working on a rather simple blog with my fiancée (just a little something we want to build for ourselves) but during the project an issue of collaborative live editing came up and i wanted to get some feedback that.

I'm sure many of you are familiar with that feature (Google Docs is one good example) - it lets two or more people to edit a document live and see each other's edits in almost real time. We wanted to see something like that integrated with Drupal so we could use it for our site, but I looked around and there doesn't appear to be anything like that.

Google bought a company that originally developed a live editing program Etherpad and released their code as open source before shutting them down. I found some forum posts on drupal.org (http://drupal.org/node/705094) that call for integration of Etherpad, however there seem to be some difficulties - it's written in java or something like that. Some more googling around revealed that there's another project on github called etherpad-lite (https://github.com/Pita/etherpad-lite) that recreates and expands the functionality of the original Etherpad. On top of that it seems to provide a php client and a jQuery plugin.

So i guess the question is, how hard would it be to integrate it with Drupal7 to facilitate node editing? And is anyone willing to give it a try?
