I'm right now working on it. If you only need 2-3 ns accuracy  between the two boards then you can do this already now without firmware upgrade. The software for this is in principle ready, but I have to 
finish the documentation. Since I'm on a business travel right now this might take me some time (weeks?). 

If you want better timing (O(100ps)) between the boards, then you will need a firmware update. Or you wait until we ship boards with the new firmware. I will announce this through this forum.
