Google docs integration with book module

This is my dream:

I have a book I want collaboration on. The book must be in a document format for printing as a good-quality handbook as well as being an online resource.

I would like to have the book in google docs and then publish it as book nodes, with separate nodes for each sub-section (header 2).

People would then be able to comment on the nodes using normal drupal comment. These comments would show up in the google doc.

Any editing revisions should eb synchronisable between google docs and the drupal nodes.

How does that sound? It would be amazing to be able to just "print an up-to-date version of this handbook" in pdf format that made sense when it was printed out onto paper (the settings would be set up in google docs).

Hope this is nearer to fact than fantasy...
