1. You forgot getting a Library of Congress catalog number and then typesetting that text block (typesetting of L/C data is a bit peculiar). Without L/C information you won't have any library sales.
2. Your typesetting saga is a good argument for using LaTex over InDesign. Why not stand on the shoulders of giants? If you like the Tufte design format, just use the Tufte LaTex package. No need to reinvent the wheel.
3. The PDF format is page-size agnostic. If people would create them in a friendlier format, say 6x9in or so instead of lettersize or A4; they would be easy to read on tablets.
