Another interesting possibility, which I almost wrote about, is robotic warfare. If there are truckloads of robot shells in the combat zone and US troops who clock into at an office building in the US to pilot them, how can an enemy fight that? Every time you destroy a bot, another one walks out of the warehouse. Our soldiers are already trained for this. Just like a video game, you get 'killed' then respawn.
Actually, you can do better than that. Having a one brain:one robot shell doesn't scale as well as having one brain:many robots. There is currently work in DARPA on getting one person to manipulate swarms of robots, instead of micromanaging them all.
Sounds like RTS for the battle field. Can't wait for they day when teenage Supreme Commander experts take out entire countries using point and click control of swarms of robots.
