A little bit off-topic: I think that another accessibility-related applications which might benefit those who have physical limitations is lineak (http://lineak.sourceforge.net/). It allows to map those new keys on multimedia keyboard that can be used to launch application (or even switch off the PC) using special keys. It might be considered for future inclusion in next releases of KDE (maybe combined with KHotKeys).
just my 0.2c.
