Dynamic Video Training

A while ago, I had an idea to make interactive video content, that would change the contents of the page based on your location in the video.  Today, its here.  Its very basic in its operations, but related content shows up in time with the video.  I have the first training video on the site as well.  Here's an example of how the content changes over time: (http://www.LearnBuildPlay.com -> Training...)

I plan to have more videos that work with this, and I also plan to create a forum that includes being able to post against a specific time in a video, and not the entire video as most other video sites do.  Its  a work in progress, and will need some considerations along the way.  Please let me know what you think, and if you have any ideas to improve it.
