Thats what the debian-mirror script does (its about halve of the
script just for that). It also uses old tar.gz, orig.tar.gz, diff.gz
and dsc files.

Of cause, but forget it with compressed data.

I'm currently discussing some changes to the rsync client with some
people from the rsync ML which would uncompress compressed data on the
client side (no changes to the server) and rsync those. Sounds like
not improving anything, but when reading the full description on this
it actually does.
Before that rsyncing new debs with old once hardly ever saves
anything. Where it hels is with big packages like xfree, where several
packages are identical between releases.
