You can unpack contain of gzipped or bzipped files and deltify it, but
you cannot restore exactly the same gzip or bzip file based on its
content unless you use exactly the same version of compressor that was
used to create the original file. So, if you put any .deb file in such
a system, you will get back a different .deb file (with a different SHA1).
So, aside high CPU and memory requirements, this system cannot work in
principle unless all users have exactly the same version of a compressor.
