Who would have thought that when the Galaxy Nexus was announced with no hardware navigation keys, that devs would grab that idea and blaze these kinds of trails with it. Take the AOKP team for example, who has created a way to embed multiple widgets into the nav bar that can be accessed from any screen and are also swipe-able. From what we understand, this specific feature is not 100% ready for public release yet, but it certainly seems like they are getting close.
Impressed? I am.
