That "multi-level expanding/shrinking" idea is very nice, but it would only work if my final product were only digital. Which it isn't (PDF).
If my customers were only "normal" engineers, I could probably get this idea through. Unfortunately there are also pharmaceuts among them and they love paper so much .

for navigation, hyperlinks work.  The links may be in the blocks, the pages, or even TOC.  i would think the navigation, organization in Visio would translate into the PDF.  I did a 150 pg Visio document detailing a sound system and then published to pdf.  The pdf navigates just fine.
