Firstly dired should uses dired-read-dir-and-switches which in turn
uses read-directory-name and not read-file-name which we could expect.
I believe this is todo.

Secondly from the definition of read-directory-name we can deduce that
it will not work as long as PREDICATE argument in read-file-name() is
not respected. I wrote about this in another thread today here on
gnu.emacs.help.

Definition follows

(defun read-directory-name (prompt &optional dir default-dirname
mustmatch initial)
  "..."
  (unless dir
    (setq dir default-directory))
  (read-file-name prompt dir (or default-dirname
				 (if initial (expand-file-name initial dir)
				   dir))
		  mustmatch initial
		  'file-directory-p))
