Since Geoserver is such a nice implementation of the OGC standards, I decided to include WorldWind .bil format elevation output to it. The deployment of data is a breeze, just point geoserver to your file. There is already imagery output as .dds plugin written by an enterprising french man, but it requires maintainance. I will probably take over both of this "Map Producers" and get them tested and maintained as part of core geoserver.
Then we will have a proper Java WorldWind stack from serving to consuming and displaying.
