It is very useful in interactive/virtual sex titles. Particularly in Zero Tolerance's Virtual Sex series. Other than that, I like the idea of multi angle, but it has seldom been that great in practice. I have seen features that had it, but angle one was edited from both cameras, and angle two was simply the footage they didn't use in angle one. So with either angle it would still flip back and forth from both cameras, and you didn't get to watch from only one camera angle if one angle was more arousing than the other. But I totally agree that it would be useful in group scenes, especially if they don't care about the different cameras being in the view of each other.
