Thank you. I've been keeping my eye out for such an app, but it missed this one. I had the old clunky AirPlay receiver app that came out when the technology was first added to iOS, but it stopped working a while ago.
This is what I'd really like to see. AirPlay should natively support streaming in any direction between any Apple devices.
Imagine, I'm watching a movie with my family, and I offer to go get dessert for everyone. Either the movie has to be paused, or I have to miss some of it. But, is I could mirror the big screen on my iPad, I could take the movie with me...
