I like the idea, but ease of search-ability is a must. Is the ability to have a preview video not in the app store? ( don't yet have mine, so I don't visit much) If not I think that would be the better option. Instead of having people have to go the video section to download or view a streaming video then have to go back to their page to finally decide to download the app. Point is video would be great, but if not easy then people won't care. They will simply download the app and try it instead of trying to find the video in a separate section.
