rendition of buildings in several cities (e.g. Denver). Is there a way to program TP do d/l them too? Download is pretty slow even with Foofle, so I guess it would take time in TP as well but it gives a very realistic look (given that the objects are accurately placed to begin with). That would add another d/l line, but it seems to be the same principle and chances are that the number of cities will increase.

No, there's no way to get the buildings or the mesh from them. Maybe if you sent a couple of million dollars their way...
