-     *
-     * (1) The user chooses a chat room or user with which she wants to share a whiteboard.
-     *
-     * (2) This invokes the appropriate doShare() method in Pedro's GUI.

-     * (3) doShare() invokes code to create a new Inkscape desktop with a blank document.
-     * This desktop will use InkboardDocument (and hence InkboardSession) for transaction
-     * management.
-	 *
-     * (4) Inkboard setup and operation proceeds as it did in the Loudmouth-based code.
-     *
-     * (3) and (4) will probably need tweaking (for example, it's probably a bad idea to
