 The only answer to the problem you pose is to not have any options. Your
conclusion is completely dependant upon who "C" is. Some make "A" change and
some make "B" change. And if "C" has implemented a SCSI-4 bit reserved in
SCSI-3 after 3 million drives are shipped they will be delighted to get all the
