2-way redstone repeaters. Simply place 2 repeaters facing into each other. The plugin detects the changing state of the repeaters and will flip one the other direction to provide signal in either direction.
Note: there is a known glitch which can happen when both repeaters are powered at the same time, as can be seen in the video above.
