Putting on googles, I think this lens use would be limited. Personally I would find it annoying. It gets floor space because gaming is a big market.
Virtual tours scrolling around on your screen, zooming in and zooming out like you can do on Google Earth street view, it would have many uses.
I could think of uses for such a lens and video even in my industry, videoing a project during or after construction.
I think it would be just a novelty item for me to own the lens for my own personal use.

Also, I suggest being there in person for your kid's birthday parties.
Unless the party is with the ex-wife, and I can tell you there is no way in hell mine is going to shoot a video for me to watch.
