And I am worried about security issues when we have thousands of users all wanting to update their little piece of the earth :-) Also as the scenery gets more populated the problem will eventually become intractable with out some division, and not everyone will want or need high res scenery for the entire planet. i.e. the Scenery requirements for a 737 flying at altitude are quite different then for a C172 pilots local airport. So I thnk that we want multiple levels of Scenery where the Global Scenery is fairly lowres except at one or possibly two default locations and any higher data is maintained by a federation of Scenery builders. We just need to define the standards by which the federation must conform to tobe directly pluggable as 'better' replacements for tiles in the global scenery base. Using a rsync analogy one could even automagically choose the appropriate scenery server based on position, altitude and personal preference or sensor model. Think quicksort and similar problem space subdivision because eventually everyone is going to want their home turf modeled as well as possible and this will be impossible todo in a non-distributed way.
