The engineers at Intuitive Aerial, a company that makes aerial camera rigs, hooked the Rift up to a drone's cameras, feeding a video stream through a Wi-Fi-connected laptop. That means the pilot can see what the drone sees, almost in real-time. (The latency's slight: just 120 milliseconds between the drone's cameras and the pilot.) But there's at least one problem with the rig: since the drone needs a Wi-Fi connection, it doesn't work past, at most, 100 meters. But still, the real world has pretty great resolution.
