Just added support for turning on and off lights via GPIO. The implementation is pretty straightforward and really just geared towards relays - such as the PowerSwitch Tail II (http://www.powerswitchtail.com/Pages/default.aspx). Now I can flip the lights on in the garage and peep around, rather than building a light ring around the camera. And it so happened my overhead LED light bar didn't have an on/off switch ANYWAYS, so two wins in one!
