Look at jigdo. As I recall, you can start a jigdo construction of an iso by first giving an iso that is almost right, i.e. the prior rev. , and then proceeding to download only the corrections that are needed. It is covered in the jigdo instructions, or FAQ, don't remember exactly.
It seems the jigdo files are not updated at the time being. The images are dated 19-Dec-2002 for r1. May be they are working on it. raj
