They tested it on Blue Fire, which I have heard is a great aggressive looping ride, so in theory anything.
My sense is that the most bang for there buck is to focus on family style powered rides like Thunder Run. You don't need aggressive physical forces as the visual effect creates the illusion of more extreme movement. If I recall they followed the thunder run track exactly at the start but then as the ride went on the movements become more extreme. I believe they faked some jumps and the effect of negative gs and even a looping element that felt almost real. Plus the animations as least on Thunder Run as previously stated were really cartoony so the initial focus will likely be on family rides.
