Hartwig, Another option is to use osgEarth to project & render each version at run time. Just create one Map object for each projection, and create a MapNode to render each Map. Point all your Maps at the same source data (GeoTIFFs or whatever). It will reproject the data separately for each map, caching the reprojected data if you so desire.
