To me it would mean to have something written in the page’s source that 
would trigger emacs to be launched, and possibly its window to be 
displayed as part of the page (that is: without decoration or ability to 
be moved, and it would scroll with the page’s content and wouldn’t be 
displayed if the browser’s window’s not).

What I would imagine would be for instance <embed src="file.c" /> or 
possibly with attributes specifying that we want to open it with emacs or 
at line n (I’m sure standards exist for those, there is certainly some 
anchor syntax for within github to point at a line, something like 
file.c#l123).

Oh that’s a valid concern I didn’t thought about…

Indeed.

open at line, open with a certain mode enabled, open several files at once, 
open an svg file either as an image or as source, etc.

the main one being “open at line”

Yes of course.

As I said: I think the way I propose would be strictly in benefit of emacs 
(it would drag people from the browser to emacs, which is going to be more 
full-featured and faster anyway). It would also for users because it would 
remove the need for javascript in certain cases that are going to 
proliferate (people programming inside their browser), so they could avoid 
it.
