Using dpkg-repack scares me a bit TBH. Other than that, I like the
zync idea a lot. The only problem is that zsync needs to be told how
to deal with the data.tar and that we need a way to either recontruct
the same md5 sum of the zsynced deb or a different way to check the
authentication of the package. Writing a apt method to zsync stuff
shouldn't be that complicated then.

We can do that today in apt with the
