I may be wrong, but I don't believe rsync actually copies diffs. I think
it copies the whole changed file. I also believe there's less chatter. But
the whole point is a bit moot if the IT people only want to allow one. ;-)

Yes, I'll set up a "mirroring" page with the instructions I just sent.

Actually, I use wget here, but it's probably the same. In the case of the
FTP site (which is the same as /files on the website), almost everything
is binary, so it doesn't matter much how you update.
