Hi Nicolas,

I understand all your points very well:  Too heavy changes for an
optional and still feature-incomplete patch targeting a sub-group of users.

But the provided functionality would be really handy for everybody
who writes larger documents (like a thesis) with org-mode and has to
incorporate comments made to the pdf.

This feature has been asked for on this list
https://lists.gnu.org/archive/html/emacs-orgmode/2010-08/msg01253.html
and on stackoverflow
http://stackoverflow.com/questions/9965049/how-to-use-synctex-with-org-mode

So I just want to contradict your last statement:  IMO it's worth the
trouble to get this working in orgmode.

Best,
Andreas
