Hello, Many thanks for this initiative.
As a blind user of Org-Mode, I especially appreciate tthe interest for accessibility. I am not sure I have anything useful to say on the mentionned areas, but I am hapy to help as I can. For a start, I can say that as far as I know there is no completely accessible PDF docment viewer under Linux (the OS I use). So what visually impaired people I know do on Linux is to open PDF documents in Firefox which, as a web browser, is accessible. One thing that I was wondering: why is this experimented with pdflatex rather than lualatex which seems more future-looking? Best wishes, Seb.
