Hmm, that's unfortunate. I was hoping to get this included in Etoys properly, but FFI is a no-go there. My idea was having a generic hardware-interface plugin that could input/output any number of signals (from joysticks and accelerometers over the XO's sensor port to special hardware like Scratch's PicoBoard or Phidgets etc.).

Well maybe we can at least find a common interface in Smalltalk for all the great interface-to-real-world projects ...
