To me that looks like they are just trying to show their software running on real machines. Which is why they show the whole laptop in the picture. A screenshot saying "Here it is running on a Thinkpad" doesn't have the same effect you know?

When HDMI was new one of the things that went around gamer circles was the fact that it was possible to do video capture on a second computer by daisy chaining them together. That way your game isn't compromised (as much, you probably still have higher latency) by trying to capture video.

I don't know if any modern video cards can still do that, but it might be good for these guys to look into it.
