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.
