Sorry, I meant to get to this yesterday. See my question on Emacs
StackExchange
<http://emacs.stackexchange.com/questions/12391/insert-org-id-link-at-point-via-outline-path-completion>
 and my configuration file
<https://github.com/sk8ingdom/.emacs.d/blob/master/org-mode-config/org-general.el>
where
I added this functionality. Basically, you go to insert a link with C-c
C-l, type id: <ENTER> and then you'll be prompted to find the org-id via
outline completion. I've reproduced the code below for convenience:

#+BEGIN_SRC emacs-lisp
;; Add ID properties to all headlines in the current file which do not
already have one
(defun my/org-add-ids-to-headlines-in-file ()
(interactive)
(org-map-entries 'org-id-get-create))
#+END_SRC

The other responses look good as well. Hope this helps!
