That's true, but I kinda feel that this stuff is something that nobody
uses -- it's a fun trick, but you can't do much with it.  That is, you
can load "http://www.example.com" as a file, but you can't save it, so...

It's a fun toy and a demonstration of how you can hook into the Emacs
file machinery.  But if you're writing code that's actually going to be
used (like browse-url-emacs), it's the worst way.
