Here is a real minimal example:

#+BEGIN_SRC emacs-lisp
(defun a-func (start end path bracketp)
  (let ((d (concat "@" path)))
    (set-text-properties start end `(display ,d))))


(org-link-set-parameters "alink"
                         :activate-func 'a-func)
#+END_SRC

it has some problems, and you might need to add additional cursor-sensor
type functions to remove the properties for editing, for example. That will
be tricky to get just right.
