Is it possible to have all the map data come from local server instead of Google Earth or Bing Map but still use their tools as front end.
For example Bing Map control (from their SDK) would be talking to some local server in the network. I want this kind of setup in a place where there is no internet and the client wants to use Bing Map toolset. Same question applies to Google Earth.
OR is it that its only possible with something like ArcGIS like server software but in that case Google Earth or Bing Map control won't be its front end.

(note: the middle step is the important part 'private map data')
