As I understand, Fedora 9 was to have deltarpms by default, but it did not get through :(, OpenSuse uses them that is a + for them, As far as debian/ubuntu is concerned I cannot comment on them.  But to update a rawhide machine/fedora 9 machine with dialup and that size of MB is pointless.  I willa get back to testing when I have access to a higher speed connection last week in August.  As of now I have to be selective as to which updates I pick up like kernel updates and such.
