OK, I think you can do a bidirectional line this way with a $1 SSR (solid state relay)...maybe
http://www.mouser.com/ProductDetail/Sharp-Microelectronics/PR26MF11NSZF/?qs=sGAEpiMZZMvD44QvxK4%2fifSkPJVuODho I use these primarily for a MCU (like a BBB GPIO out) to driver stage in like ESC circuits, or to drive a beefier electromechanical relay. Right price, really versatile.
