Stereo HMD and experimenter's monitor

[Vaquero]

Thanks Jeff, with your help I managed to get the second window to show up and made the stationary view follow a tracker. However, there's a problem with the live character. While it's correctly shown in the view of the oculus rift, the character just stands in its T-pose in the other client window as you can see in the attached picture.
What's the workaround for that? Do I need to load a another Live Characters Device instance into MotionBuilder and set another port or something?
Or is what's happening in one client simply not shared by the others (»Note: Co-presence is not supported on a local cluster.«)?
So I would need to connect another machine to the network and start a vizard client to have 2 different windows into the same shared world?
