I was intrigued by this New York Times article, which talks about how Kindoma's new Storytime app lets grandparents and others read bedtime books remotely to children.
Another possible application: authors doing remote readings for small groups of students? Or larger groups, if the iPad is hooked up to a larger display.
I haven't yet tried the app, but the catch is that the app has to have the book in its library. Once the tech is streamlined and if successful, however, perhaps publishers would want to partner with Kindoma to make titles available.
