 *    Intended
 *    Method   If we're already authorized, just return TRUE.
 *             Otherwise, make sure the comm channel to the server
 *             isn't busy.  If it is, put up a message to that
 *             effect and quit.
 *             If not busy, get authorization information from the
 *             user and present it to the server (in encoded form).
 *             Wait until the server responds or until the Abort
 *             Protocol flag is set (by the user via a menu).
 *             If authorized, return TRUE, else put up a
 *             message to the user and return FALSE.
