I thought that part was interesting. How did they sync up? She was on his home network so the default is his stream? This also implies that there is some kind of stream syncing problem. What if we are in a public place and we all watch slightly different streams? We all have separate experiences? Who gets the rights to different public streams? How many billboards are currently showing on this blank white canvas on the highway? How many virtual worlds are currently overlapping the real world and who has the rights to the default one?
