For public annotations that is great.

For private annotations with hypothes.is one can install it on own
server and protect system for one's own group. That will do only a
group that is serious enough or have serious demands for annotations.

Myself I do not prefer having too much software installed online
especially not databases that are private. What is private I keep off
the Internet. If I wish to communicate over Internet to somebody I
always establish first encrypted line. So I am about to develop system
to provide annotation to somebody over Internet, without compromising
security of the file or annotation.

As each hyperdocument has its unique ID, it is easy to expand it into:

example.com/1/2/3/4 for ID 1234

That would be HTML with PDF annotation where user could open PDF
inside of that HTML or click on the PDF to open it. I do hope that
pdfjs does support specific page jumps. And such annotation on HTML
should work with or without Javascript. Those without can simply open
PDF file and manually jump to specific page as annotated and
instructed.

iceweasel-uxp on Hyperbola GNU/Linux-libre does not have pdfjs
built-in as I see it, GNU Icecat has it.

Then I would inject web server password protection and protect it from
public. But that does not protect the document of those who could
intrude into the server and also does not protect from cracking
attempts as username and password are not alone well secure. Better
would be having the encrypted HTML that is protected by user's private
PGP key, but I have no idea if such technology exists yet.

It seems that the framework exists:
https://www.w3.org/Conferences/WWW4/Papers2/245.html

but it is unclear which browsers would support such displaying of PGP
encrypted data. With Emacs it would be trivial, but asking variety of
users to install Emacs is not convenient though desired.

Workflow would be:

1. Annotate PDF, provide maybe personalized assignment.

2. Hit key. This would then cause annoation to be published with the
   hyperlink to PDF and page reference, it would encrypt and prepare
   the file for reomte user including it would inform remote user by
   email and SMS of the assignment. No tedious copy and paste.

3. User would report if it is done or not done. Reporting could be
   done also by single click or report written followed by click (HTTP
   POST). Best would be if report is PGP signed by user's verified and
   trusted key to have proper tracking and evidnece of the action.

Same workflow could be implemented from Org type of annotations.
