That would be a neat usecase but it's not a slam dunk. TEEs in theory eliminate the need for the user to trust the owner of the hardware. But for a cloud you need to eliminate the other direction too. Cloud companies achieve this by... Spending a LOT of money on it. And the technical project of doing that is easier, because they control the whole host stack. I'm not sure it's technically feasible to achieve that in an environment where the host also needs to also support stuff like running Steam! But still, maybe if you constrained the requirements enough it could be possible, it would have been a really cool thing to try!
