Other options for 3dof on Viture XR Pro without Spacewalker

Does any of the accessory hardware (neckband, dock, or adapters) enable 3dof when plugging a Viture XP Pro into a computer without running spacewalker? One of the great selling points is not having to run any local software to use the glasses but with 3dof not enabled on the pros it makes it harder to use to not be able to pin the screen. I know spacewalker solves this but if I can't run it, does any of the other hardware help solve this problem?
