This thread is first time I hear about V2H. (I don’t have any car yet, electric or otherwise.)
It sounds amazing. Only thing I wonder if it can even be set up so that it will be like an Uninterruptible Power Supply. So that when there is a blackout, the V2H supplies all the power without any interruption.
I have several computers but no UPS yet. Imagine if I could buy an electric car and when I am not using it, my car is UPS for my whole house including my computers! :D

That's the point of V2H (or a residential battery, which it emulates). Although you still want a UPS for computers: I doubt "without any interruption" is at the scale of a UPS, and possibly not at the scale a desktop computer will require. Notably it depends how the grids cuts off, if it cuts off in one shot (like throwing the breaker) the failover should be almost instantaneous, but if it fluctuates before failing the battery might need a lot longer to engage.
Yes, but you need specialized (expensive) equipment. Expect a $8-12k bill.
Will the setup outlive the car? Or will I have to replace it when I buy a new EV?
$10k amortized over 20 to 30 years is not too bad. But if I buy my first EV and only keep it for 5 to 8 years before replacing it with a different EV then I’m less happy if I also have to replace all of the additional equipment that soon.
