I tried using this as a lock screen  but it had some problems. You can't set a separate wallpaper for it. You can't set custom shortcuts for unlock areas that aren't just dialer/camera (what about SMS? or a custom activity?). It doesn't seem to block the home button if you have your system lock screen disabled. If you *don't* disable your system lock screen  it takes about 5 seconds for AC display to appear when you wake up your phone. It doesn't report widget size to widgets  so many can't work properly.
