Direct Input - ability to use game controller-like stick+buttons

[sorenhan]

Currently input abstractions are limited to click/grab. With an input solution that switches over to controller-like behaviors, a whole number of arcade games become possible. Even a minimal set of controls (a single stick, A-button, B-Button) would give a lot of freedom. It probably has to be minimal, because it has to be possible from every set of input devices that MREs support I think this would work best if you somehow "engage" the MRE that needs stick controls, and there is a standard way to "disengage".
