Book navigation – how to customize outline to show progress and enforce serial navigation

I have a task to customize Book outline to:

  • force the pages of the book to be read from start to finish. Once a page has been read it can be revisited.
  • show the progress through the book.

I was thinking of using the outline links to do this. For pages that have not been read the outline item would not be a link. Once the page has been read it becomes a link.

I am fairly new to Drupal and have some experience creating and modifying modules. It would seem that this could be accomplished by extending the Book module but I have not looked at the code yet.

Does this seem like the best way to go or is there an existing module that would help?
