apt-get (experimental only iirc) uses this to only download changes
since the last update. This has been brewing for a long time and was
previously available from people.d.o/~aba. It is now integrated into
tiffany.

Not sure about the rsyncable but it contains the timestamp and
possibly file permissions or something as gzip does. Running a gzip
Packages localy does not give an identical result. For debmirror I
rsync the Packages.gz, gunzip, rsync the Packages, bzip2, rsync the
Packages.bz2 (all only if the md5sums don't match)

zsync uses http so you already have access. What is missing are the
checksum files. Also, last I checked, zsync didn't yet have support to
sync the contents of a deb as opposed to syncing the compressed data
itself. Before that the savings are minimal at best.
