Good idea! "free running" into space. Talking to aliens certainly
needs open source hard- and software since they have to understand the
protocols first :)
But seriously, one Freerunner did go to (inner) space on a research
rocket (altitude was approx. 100 km):

I don't know exactly why Christoph & Michele developed this, but I can
imagine some areas (who finds other ones?) what that these sensors
could be used for. You develop new user interfaces (3D gaming :) and
generally improve portable navigation.
For car navigation, GPS is in most cases sufficient since a car goes
fast enough so that GPS can tell about the direction of movement. But
if you have a handheld device, only a compass and/or gyroscope can
tell that you are rotating the device. While the LIS302 accelerometers
can detect that you shake the device. This gives several new inputs
for gesture recognition. The arena is open for creativity...
And, I think one can use the pressure sensor either as a weather
station (during hiking or skiing) - or to get the altitude and detect
ascent/descent better than with GPS. I think all these fine things can
augment and integrate with the GPS system.
