All you can do with BD Live Event

Do you know all you can do with BD Live? Since Blu ray allows for Java programming I’m hoping this is just the tip of the iceberg for bonus features. Right now these seem more like gimmicks, a disk menu that reflects your time of day with weather, schedule a time to watch a movie with friends and chat together on screen, minigames, itune integration to tag and download songs from the movie, etc If this is the start, I hope the keep racking their brain to wow us with each new release.
