I have not compared zsync with pdiffs. Ubuntu does not use
pdiffs because it generates Packages files every hour, and it
seems that ruins the usability of pdiffs.
It'd be good for someone to do such a benchmark, but it does not seem
relevant for my current task.

Indeed. Thanks for your notes, they are very useful. Finding and fixing
the problems is what I'm currently looking at.
In the long run, it would be good to have checksums of .debs be done on
the uncompressed data, but that's going to require fairly invasive
changes in all sorts of places, and should be done in co-operation with
Debian. I'm looking at low-hanging fruit first.
