Hey,

I hacked together some lines of lisp that should achieve that. It's my first 
non-trivial (from my point of trivialness)
piece of code. I'm open for any suggestions:

(defun flo/org-attach-move ()
  (interactive)
  (when (org-attach-dir)
    (let ((target (read-string "Move attachments to: ")) ; read-directory-name 
here?
          (attach-dir (org-attach-dir)))

      (if (string= target "")
          (progn
            (org-entry-delete nil "ATTACH_DIR")
            (setq target (org-attach-dir t)))
        (progn
          (org-entry-put nil "ATTACH_DIR" target)
          (make-directory target t))
        )

      (unless (string= target attach-dir)
        (copy-directory attach-dir target t nil t)
        (message "Deleting %s" attach-dir)
        ;; (shell-command "rm -rf %s" attach-dir)
        )
      )
    )
  )


Best,
Florian
