How about:

rsync -av remote.mirror.site::/path/to/iso
/localpath/to/iso --partial --progress --stats

this will do effectively what diff does, and only brings down what is
required. ie if the file is the same in many places, this will only bring
down the differences, and give you an identical copy of the remote file.

it usually saves me 500MB on a 600 MB iso (one version to the next) some
times even more, sometimes less.
