A company called if mem serves "Boundless" was at Immersed in Toronto event and is working on a few methods for locomotion.
Some users have been reported using vive/valve tracking pucks to track more of the body. However we would need a v2.0 puck to be compatiable with v2.0 lighthouses.
This would be a great idea to explore making their own v2.0 tracking puck as it could be utilized to bring laser head tracking to the BE & 4k models as an addon in 3 skus.
1 Tracking puck
2 Tracking puck with 1 to 2 lighthouse
3 same as above but with 1 to 2 controllers.
Then of course dev packages with multiple pucks... So guess 4 skus. Lol

Of course this idea would need to be released at a later date probably no sooner than May 2018?
