I sense a tongue being held firmly in your cheek, but I'll play to it. There are at least a few ideas in here, if the video is representative of a trend (that has yet to be determined) or boom area.
One off the top of my head: Provision of camera and interactivity systems for concerts, so remote fans and musicians can interact better. Imagine if Folds could get 50,000 fans worldwide paying $10 to watch a gig with more interactive elements like this.
