I think I saw the slides to this once. I don't have time to watch the video right now, but if it's the same presentation, he had a point about hashing a file and then uploading the file and the hash to the same web server for download. I forget the exact words, but the point read something like, "Don't think you've accomplished anything worthwhile if you place the hash and the file on the same web server." I agree with that, but am guilty of doing it all the time (as are others). Does anyone have a link to the raw slides (PDF)? I downloaded them once, but lost them.
