What is the VR broadcast bandwidth requirement/use on the consumer end?
Is a live implementation even realistic in the short term? No, no one is producing VR webcameras at a marketable price.
1080p is limiting 720p is workable (<now>)
4K bandwidth is not realistic now for live broadcast to consumers.
Usability is a big factor -- getting past the *brick on the head* problem will determine if VR ever gets to the top of the adoption curve.
