There's a bunch of hackers trying to reverse-engineer and open-source the DataHand here (most recent reply was yesterday): https://geekhack.org/index.php?topic=41422.0 https://geekhack.org/index.php?topic=41422.0 I've had a couple of DataHands (and still keep one under my bed). It's a real marvel. For certain repetitive strain injuries: it's the only thing that helps. I'm using regular keyboards now, and I'm grateful that I can. But I look forward to the day when anybody who needs one can find one.
