You are over my head a little now :) But I was thinking of the heading 
tags. Consider the book output for the "Is Drupal right for you page

http://drupal.org/book/print/22963

The tag for that node in the HTML body is

<h1 id="22963" name="22963" class="book-h1">Is Drupal right for you?</h1>

What we need to do is also specify the parent nid in there as well. 
Drupal can then build the structure by using the heading tags to parse 
the printer-friendly version into individual nodes and build in a 
temporary array the structure using the parent nid name nid 
relationship. Wouldn't that work?
