Speaker Text: Simultaneous Video & Transcript

So I just ran across a tool that I think has some pretty cool potential for ministry, business, and media in general.  It’s called “Speaker Text” and it allows you to watch a video and a transcript of the video simultaneously.  Not only that, you can jump to anywhere in the video by simply clicking on the appropriate place in the text.  You can also copy a piece of the text, drop it in a blog post, and turn it into a link that takes readers directly to that part of the video.  Check out this demo from SpeakerText.com.   

Question:  How could you use Speaker Text in your setting?
