I'm not sure that I would've watched this as a video. Being tangentially involved -- having to actively scroll -- seems to make it more engaging. And I wouldn't have been so impressed by the website from a technical perspective.
It should end up as exactly the same experience, except possibly without the ability to turn all the way around, depending on whether or not they want to spend bandwidth on a 360° stream. (They would still need to send a slightly larger FOV than the viewport for their little mouse look effect.)
