Topic: Hardware Idea for Chumby... Use a Griffin Powermate as a control devic
Heh i do NOT have good driver skills but wouldnt an easy way to control widgets be if you used a control knob that appears as an hid class USB device...
Turn right, move to next widget, turn left, go back one widget... tap the knob, stay the widget, tap it again, unstay the widget... perhaps a double tap to mute/unmute
