StoryVisit (by Raffle et al 2011)
"StoryVisit allows children and long-distance adults to experience a sense of togetherness by reading children’s story books together over a distance. StoryVisit combines video conferencing and connected books: remote grown-up and child readers can see and hear each other, and can also see and control the same e-book."
