Great idea, but doesn't Stypi already implement this? Granted, as a disclaimer, I didn't sign up. I'm making an analysis from what the homepage says. Question - in Stypi, live typing can be overwritten by anyone else who is in the same room. Does this work the same way? Because that is a huge flaw - but then, I don't think there should be live typing at all.
