There's another angle, though: while the control round-trip might be hideous on OnLive, the inter-user round-trip is negligible; presumably everyone will be sitting on the same gigabit (or better) LAN. Games currently have to pull all sorts of tricks to make the inter-user latency appear not to be present. They've got good enough that generally you just don't notice. I think the same thing will happen here, although I admit that nobody's demonstrated that they're capable of surmounting the technical challenge, and I doubt it's as simple as tweaking #defines in the network stack.

It's a lot easier for a game to let you shoot at where your client-side prediction thinks the guy is supposed to be than to allow players to react to things that happened before their input for a given time tick was processed. What you're saying is nontrivial and may not even be workable, because it's impossible to really separate "stupid slow player" from "player whose latency is high enough that he can't react".
