Anyone demo'ed vrcade's wireless system at VRLA?

Was at VRLA on the weekend but did't think about queuing up for the vrcade demo while I was there. I am interested in the general feedback about latency and other impressions from anyone who tried it. Mocap tracking is a known quantity, but I wonder what they can squeeze over the airwaves, especially now that we're approaching 2k and higher resolutions at 75+ fps.

If you leave your comment it would be valuable to mention your previous experiences (DK, DK2, VIVE, etc.) to put the feedback into perspective.
