Ah... I actually imagined the exact opposite usage :- ).
I never do 360s "VR" for clients, rarely people ask for it. But I can imagine if we could look around in them... they would suddenly look lot more impressive. And LOT MORE than Unreal, which naturally can already provide this effect because the data in real-time is there...
That was my first thought of seeing this being used, moving around in 360s static rendered images. High quality from off-line ray-tracing, but the freedom to look like in real-time with static position (which is the future, even Half-Life Alyx has statis position because they did the research and apparently locomotion sucks).
