realtime total situational awareness for the military

Tracking of real world data into a 3d model of an area and augmented reality technologies have had great advances as of late with the ever increasing processing power of modern computers.

Bear in mind that all this is real time, today.
There are some even more impressive videos but i can't find a link at the moment.

One practical and quite feasible use of this within the next ten years would be instantaneous situational awareness for all soldiers in a unit.
For example; a unit is entering an unknown area..
Their helmets are fitted with small cameras that send the video to a remote processing station.
There a 3d model of the area is formed and human beings in the picture identified.
Other soldiers not seeing this would get a translucent wireframe presentation of surveyed areas and people seen by any member of the unit would be seen by all.

And the usual consumer applications aswell, ofcourse.
I'm sure nintendo will be among the first to come up with something.
And Google is planning something with entire cities i'm sure will be integrated into google earth at some point.
