A thought just occured to me. Get the md5 before compressing, and include
the md5 data (as a text file) inside the zip prior to transfer, then
compare that md5 that is inside the zip with the files after unzipping on
the other end. It might not work, and you may have already performed this,
but it'd be worth a shot if you haven't.
