do two identical compressions produce the same output? if so, wouldn't the same thing happened just against the compressed files?
It's not uncommon to see multiple .torrent files with the same content FYI.

Normally no, compression formats like zip are not guaranteed to produce the same output for the same input. That's why things like torrentzip and torrent7zip were created, to ensure that the same input did create the same output.
Except for so many that are a single archive file. It seems logical that you'd want to compress what you're sending as much as possible before uploading... but in today's bandwidth environment, it actually makes sense to leave certain things uncompressed so you can benefit from swarm overlaps?!? Wild!
