I like the idea of making tiling window management more accessible. I'd be very happy if we saw more of this move into the mainstream window managers and operating systems. For example, when I open two terminals in OS X they have a habit of opening one on top of the other, when I invariably would rather have them side-by-side.
More intelligent window placement will eliminate a lot of mundane window-management work for the user, leading to a more pleasant computer experience.
If you haven't tried a tiling window manager, I suggest you do, and this looks like a great way to start.
Compiz has a "smart" window placement mode where it tries to place the window in the least "dense" location on screen, preferably empty space. It fills the screen in a left-right then top-bottom search.
