It sounded like you were wondering how the sales would be calculated, which isn't a big deal. The game companies will do what they need to do with prices and licensing to continue to make money. I don't know much about the law, but if OnLive diminishes their sales, I imagine they'll just work out some sort of terms of service / activation rule that prevents their games being used in a commercial setting. Then they just work out licensing with OnLive at whatever price they need to in order to make money.

Anyway, my point was just that I don't think OnLive will make it any more difficult for game companies to make money. Whether they sell individual licenses to users, or expensive corporate licenses to streaming services, it's just a matter of crunching the numbers. So long as people want to play their games, they'll still bring in cash.
