The trouble with using 1:1 trackpads to control a cursor-based strategy game is that you always have to compromise between speed and accuracy. I'm interested by the setup they used for Papers, Please, but that still requires you to "walk" your thumbs, picking them off of the pad and setting them down at the other end again.
Preferably, you'd be able to move across the screen in a single sweep, but still be able to move the cursor in tiny increments. Which is why I'm expecting someone to make a driver like this, where you move an area quickly across the screen, and move the mouse slowly within that area.
