YouTube needs a "download" button; love this code, it works like magic, but for the average user the real answer is that YouTube needs a way to download a video; otherwise, YouTube is just enabling all the 3rd party sites that exploit YouTube making it easy to "hack" a way to download the files, but hard for the average user who ends up getting malware to download the video.
