No, it's really not Unity, it's just a custom in-app toolkit. It's a lot closer to Mozilla's XUL layer if anything. The funny part is though, that they intentionally disable 3D video acceleration, but are happy to use an OpenGL-based toolkit. The only hope is that they implement a "style engine" ala Firefox so widgets can at least look native-ish rather than Chromium sticking out like a sore thumb. edit: Oh I read the document you're talking about now. The Shell is specific to ChromeOS. It lets them use the same Aura code in the compositor and the apps, so they get a win there. It's very likely this is to go along with ChromeOS's switch to Wayland or a Wayland-like display protocol at some point in the future.
