Pulling focus in 3D

I had a Q&A w/ Brian Hubbard the other day and he was asked about how he pulled focus on Archangel, a trailer for a feature shot in 3D on a P+S Technik rig and he kinda glanced over the question by saying with 2 wireless remote systems. I was wondering if anyone has experience with this if you can hook up 2 FF units to one Reciever to get the focus exactly correct on both lenses with both pulls being exactly the same. It seems like quite the feat to do this with 2 people.
I would think it would be easy with a couple of wireless systems (Prestons?) with two receivers on a single frequency and one transmitter. Both receivers receive the same info via the wireless. The issue is matching the lenses, so they are in focus at the same place. This would be a mechanical issue with the focus mechanisms (helicals) traveling the same distances in order to get both lenses to the same distance.
