Feature: Ability to track head movements

I'm loving the new Virtual Monitoring Pro. It's a real step up from some of the other virtual monitoring systems I've used. 

One feature that I miss from other systems, though, is the ability to track head movements via video or (preferably) a sensor mounted to the headphones. 

I find that this movement tracking really adds to the realism of mixing in front of actual speakers.

Anyway, that's my two cents!
