Take my favorite thought experiment. Suppose I design two Mars Rovers and I want

distribute the artificial intelligence between the two of them, using data links so
whatever one sees the other sees (incidentally this, minus the AI, is what combat
aircraft software does now) and so there is a single top level decision routine on
top of local decision routines about maneuvering around obstacles and managing
internal states.
OK, I'll bite. That AI program is running on the combination of the two pieces of
hardware, this is no different than how Watson
<http://www.usatoday.com/tech/news/2011-01-14-ibm-jeopardy_N.htm> runs on a much of
connected servers. But think about it, does not the data correlated to the sensors on
one of the Rovers have to be synchronized with the data from the other Rover so that
their manuevering can be controled. How exactly is the internal model of this system
built so that it can 'consider itself' as being both exploring some pile of rocks east
of Mt. Olympus while the other Rover is taking a dirt sample in some crater 500
kilometers away. It is not possible for two fixed points to exist on one compact and
closed manifold. You can only have one at a time. What you describe is more like a
Rover with a multiple personality disorder.
You're suffering from a failure of imagination. It can make a model in which it
considers itself has having to bodies at two different places. It wouldn't even be
hard to program. If you can experience two different places and you can act in two
different places you ARE in two different places.

Hi Brent,
Could you give us a brief explanation of how this would work? I will readily admit
to a failure of imagination here.
Just as you have two eyes providing two 2D views of the world which your brain merges into
one 3D model, one can merge the data streams from many different sensors located in
disparate places to create a single unified model. Military systems do this for
battlefield awareness. And this model can include a 'self'. The self is usually located
where the hardware is because evolution requires that the hardware/self be protected.
Brent
Onward!
Stephen
