Syncing two cameras

[ItsMeLenny]

I question how pointless this feature would be:

I do recall a few years ago checking out something that was like a CHDK fork (SDM) which allowed two point and shoot cameras to focus and capture the same as each other to allow for 3D photography.

Ultimately after syncing start/stop of a video the next problem is focus (usually needing an accurate duel follow focus rig) but ML has the option to focus via the arrow buttons, can these output so that when the button is pressed on one camera the other camera can detect it as well?
