I'd be really wary of implementing something like this. It would likely be a shortcut to chunder city.
Even very slow translations which are not user controlled can be incredibly uncomfortable.
Another issue will arise from deciding which way is up for your 'track' - which will almost certainly twist. Imposed rotations (i.e. not arising from headtracking) along the camera axis are extremely unpleasant in VR (indeed they are generally avoided even in flat games).
