I think this is a very useful tool if working with arbitrary file changes on block devices, but it's still very low level and would need a crapton of modification/wrapping to make it useful in a complex system. I would rather use Kickstart or the like to distribute changes intelligently, or barring that, rsyncing hardlinked directory trees, or zsync (but RPM/Yum would really be ideal due to the features gained)
