One more issue, still in the vein of "not enough metadata". Your comment
reminds me: most GIS data is in projected coordinates, and many GIS
formats do not include embedded spatial reference system information. So
a large quantity of the data in the system would not be locatable on the
globe. The metadata about what coordinate system the data is in would be
critical to providing a useful spatial search routine. I think this
particular problem is the real sticking point to making a practical
implementation.
