I've proceeded with my little project using the dynamic block, since it
seems that this is what it was designed for. I wrote the following bit of
code and would appreciate answers to a couple of questions.

#+begin_src emacs-lisp :results silent
(defun flatten-string-with-links (str)
  (let* ((newstr str))
    ; find [[link][desc]] and replace with 'desc.
    (setq newstr (replace-regexp-in-string
"\\[\\[[^\\[]+\\]\\[[^//[]+\\]\\]"
                (lambda (s) (save-match-data
                         (nth 2 (split-string s "[\]\[]+")))) newstr))
    ; find [[link]] and replace with 'link.
    (setq newstr (replace-regexp-in-string "\\[\\[[^\\[]+\\]\\]"
    (lambda(s) (save-match-data
      (nth 1 (split-string s "[\]\[]+")))) newstr))
  newstr))

(defun org-dblock-write:tagged (params)
  (insert (mapconcat 'identity
     (org-map-entries
      (lambda()
 (let* (link desc innerlink)
  (setq desc (nth 4 (org-heading-components)))
  (setq desc (flatten-string-with-links desc))
  (setq link (concat "file:"
     (abbreviate-file-name (buffer-file-name (buffer-base-buffer)))
     "::"
     (org-make-org-heading-search-string)))
  (org-make-link-string link desc)))
 (plist-get params :tag)
(plist-get params :scope))
      "\n")))
 #+end_src

* example       :links:
** not a link
** [[http://google.com][link]]
** some text.[[http://google.com][link]]
** [[http://google.com]]
** some text. [[http://google.com][link]]. more text.
[[http://google.com][link]].
final text.

Q1: I've tried to leverage as much built-in org functionality as possible,
but deeply suspect that I'm overlooking some, since agendas do much of this
work.  Is there a simpler solution than mine?

Q2: The link generated for the last item ("broken link") does not work.
 Removing the "%" from the URL fixes it.  This seems to be a bug
in org-make-org-heading-search-string?  Or am I misusing it?

Any help would be greatly appreciated.
