What I have done is used Vagrant for a development box, which included
text Emacs. That worked well.

I have not moved this forward yet as an Org mode box with a GUI. When
the topic came up here, it got me thinking about doing this again. My
other motivation is to move to 100% VM based workstations, and this
seems like a perfect way to get some re-use out of my Emacs/Org box.

Thank you for the suggestion. I'm already doing something similar:
#+begin_src emacs-lisp
(let ((link (org-store-link nil))
  (name (org-element-property :raw-value (org-element-at-point
...)
#+end_src

For some reason I was under the impression that org-element might be
overkill for this, but it works well.

Thanks again,

Alan

Off the top of my head I assume that the user has high speed Internet,
many GiBs of disk space, a few GiBs of RAM, and a couple of CPUs to
run the VM.

Include Xorg so as to be able to run GUI Emacs.

Re: [O] PDF-tools... and LaTeX (solved)

Sorry for the noise, to use PDF Tools instead of Okular I just had to write 
into my .emacs:

(pdf-tools-install) 

 (TeX-view-program-selection (quote (((output-dvi style-pstricks) "dvips and 
gv") (output-dvi "xdvi") (output-pdf "PDF Tools") (output-html "xdg-open"

Yes, well, this is already part of the code I posted, see above. However, 
thank you, I admit my question is a little bit OT!

I made a docker image for my xwidget emacs branch:
https://github.com/jave/xwidget-aux/tree/master/emacs-xwidget-docker-debian

There are notes there also how to run the dockerized emacs in graphical mode by
forwarding X. 

It would be very straightforward to use the same technique with plain
gnu emacs rather than my branch.

Have you seen this: https://github.com/MobileOrg/mobileorg?  Anyway,
.org files are just plain text files so any editor will suffice.
