The attached scripts could be a starting point. The rsync batch to create the DVD out of the CD isos is only 60MB, and the other way round creates ~15MB files. Reconstructing a tarball of the x86_64 SRPMS given the i386 SRPMS takes about 60MBs too. I have other scripts (not posted) to extract file lists from isos and create rsync-priming isos out of a local copy of rawhide. However, I didn't see much point in pursuing this for this case, given that it's a pain to obtain the exploded tree in the first place, unless you happen to have access to an rsync server offering them. It's far more network-efficient to obtain the isos and then explode them, than the other way round.
