I'd love to know how much these VR experiences are going to cost. At that resolution, they're probably using GTX 1080-equipped PCs. Without knowing the price of these HMDs, I figure the total hardware cost per user must be
at least $2.5k.
Anyway, it's a good move for StarVR. They don't have to compete with Vive's freedom of movement or Rift's price tag. And this gets them some PR, and might drive demand from a few price-insensitive buyers who are impressed by the experience.
From IMAX's perspective, one benefit of a VR experience (as compared with a film) is that you could vary it a bit, each time. Give people more reasons to come back. On the down side, I'm guessing they'll be targeting collective experiences, without much interactivity.

That's no worse than the shared helmets at a go-cart place. Some people will find it totally unacceptable, fearing lice and other critters, others will be OK with it.
I don't know about you, but the few karting places I've gone had clean head socks to use. I prefer to bring my own helmet, though.
