To use Youtube's API, a developer must acquire a Developer ID - this is an additional property that is attached to the developer's YouTube account. The information that is available to developers is similar to the information that can be acquired by accessing YouTube's many RSS feeds.
YouMashTube uses the YouTube API to let users drag and drop videos into a playlist and save it as a webpage.
