I had thought that Poser could import BVH files with relative ease. I would think that they only need to concentrate on the facial motion capture methods. But then I may be wrong.
I'm looking forward to more detailed hand capture.

Hello:
Yes, you can capture full body and display into MotionBuilder in realtime. You should also be able to drive facial points in MB in real time.
Yes, Poser does support BVH, but not very well, you can only import about a minute or so of data, longer captures cause lots of problems.

Hey back to facial capture for a moment. Is there a graph anywhere detailing exactly HOW the cameras should be set up for facial capture? (I just got my 8 camera setup a few days ago but have yet to bust it open yet)
Should the model maybe sit on a stool and have all 8 cameras a couple of feet from their head going around the model 360 degrees? I'm not sure...

Hello:
Just to clarify, we have not released any facial mocap software at this time. Arena will have an add-on for direct facial mocap support in the near future, or you can email us to become part of the advanced test group.
For desktop facial mocap, we have found that sitting on a stool is best, with around 6 cameras placed in front of the user, 3 low and 3 high, in a semi-circle type pattern. The cameras should be about 3 feet away from the users head.
Once the official product is out, we will have setup diagrams and all other needed support materials.

Here is a sample of the tennis player BVH from the Optitrack website, used with a poser model at 25fps, no modifications done, straight import.

Sorry. Just to fully clarify...
Is it possible right now with a 8 camera set up (and Arena software) to capture a facial animation point-cloud and export that out to Motionbuilder to drive an actor's face?
What would the Arena expressions add?

No, currently it is not possible to export a facial model directly to an application, like MB, and drive an actors face.
The Expression software will allow you to do that, when it is released.
