enabling different outputs for vive/oculus and pc screen (comparable to unity feature)

Hey, there were several posts in November last year saying some kind of local multiplayer would be possible soon.
I found a workaround running 2 instances of the game and connecting them locally, but that cant really be a valid permanent solution.
There are so many different interesting game concepts possible with that feature and i wanted to know if there is an ETA on when to expect different outputs for HMD and PC screen implemented.
