Present live streaming video to your readers, right from within the iBook!
With this widget you can place an embedded version of any Ustream video into your book. As the video is streamed live, it will not take up a lot of space in the book and you can optionally specify a holding image and only show the video at specific times e.g. at a conference, lecture or seminar. You can also make changes to what is shown in the widget and push this out to the book, even after publishing.
