Ah, but therein lies the core problem: a zip file can be considered identical as
long as it contains the same collection of files, even if the files are stored
*in a different order.* Unless you ensure that OO (or whatever) consistently
stores all of the files in the same order in its archives, two zip files may be
identical in content, but very different binaries. This may be a nonissue or it
may be the end of the discussion...
