Wow, as usual thanks Nick, great help and insights. Say, LaTeX and xpdf and poppler and Okular are all great software--suggest you try out xournal too:
apt-get install xournal --shows .pdfs and many tools for editing .pdf's Also, you're well aware of the Emacs/ELisp tools for .pdf's ( https://github.com/politza/pdf-tools); but, suggest you install and tinker with CPAN/Perl's pdf-tools--well worth investigating.
