there's some unity plugin the nips made to do mocap with the vive trackers + finalIK and bake it into an animation. It was somewhere in vket, can't find it at a glance though.

the trackers do offer submillimeter precision which is definitely better than kinect. you could potentially use them to make 3d scans more accurate by rubbing the tracker all along the outside of an object to generate a surface point cloud. Probably more hassle than it's worth though since photogrammetry is pretty good already.
