Doing stenography is one example - at any time you could be pressing up to 2 keys with every digit on your hands. If you were creating your own steno device, it'd be easier to make it HID compatible, since every system of importance supports it and would avoid the need to write new drivers. The Plover software (http://plover.stenoknight.com/ http://plover.stenoknight.com/) can be used to provide steno for regular HID devices - works with any N-key roll-over keyboard.
