Anyone seen this? Should be able to use Bluetooth for headtracking with build in gyro, accelerometer, digital compass module. All for USD 19.90. Not sure on the update rate and accuracy.

It won't work like you want it to.
It can only tell you if you're getting nearer or further from something, that you are somewhere on the surface of a sphere in relation to the station.
To quadrilaterate your position you need at least 4 antennae on one of the modules.
What I can't find information on is whether the beamforming technology in wifi 802.11ad (WiGig) modules can report receiver relative position.
