I definitely like the thing about integrating smaller-tiled SRTM data into the Marble/KDE environment, which will give independency to external servers. (And I really had some headache about Nasa putting the tiles in different folders for each continent, doesn't make the automatic downloading easier...)

Florian: No problem. I'm sure only few people knew about Niko's efforts. It would be great if you could combine your floatitem code with Niko's efforts. I just looked through the FloatItem code and it looks pretty sophisticated - very good work!
