Tangential to this. Does anyone know of an app/service like etherpad, but for handwritten notes? Would love to be able to replay notes that I write with the pencil on the iPad. I also feel it would enable a cool way of storytelling in which you can play with the way you write so readers get to experience the text in different ways. Imagine that as you are reading something all of a sudden the letters start getting bigger, or thicker, or star changing color. Anyway, just replaying handwritten notes would be nice.
