Comment 1 for bug 1030101

(few more thoughts...)

1. Will need a new column in the movies db table to store the key
2. User should probably have the option to view/save this key in case their browser cache gets wiped
3. Should we also limit MP4/WebM downloads to the user's who created the movie? This should help to further discourage users from uploading movies created by other users (although this wouldn't prevent that since it's pretty simple to download movies in an HTML5 video element).
