OK.. this isn't the answer to the mainstream use of cybiko, but it made me think of something similar. If you had a bunch of bluetooth enabled laptops [or wifi for that matter], say in a conference room. They should be all capable of talking to each other, right? So, what about some kind of digital dry-erase board that can be shared by everyone in the room? That way, at the end of the meeting, everyone already has a digital copy of the notes made. Everyone's doodlings could automatically be transmitted to a projector, for display. It needs some thought on how to allocate "board" space to each user. I see it being useful for people who do any schematic or drawing based group discussions.
