    I'm personally a fan of the Winkel Tripel for this map:

    Winkel Tripel is a fine projection for a global map, but it's not a particularly good choice for larger scale maps. Flex Projector lacks any suitable projections for larger scale maps like conics, azimuthals, or transverse Mercator.

    I've also used Hugin to re-project equirectangular, but again, it is a limited subset. Can you suggest any raster re-projection software?

    G.Projector if you want something easy to use, but fairly limited, it's likewise focused on full globe projections, and doesn't support vector data at all but does support conic and azimuthal projections. The command line tools for GDAL/OGR or a full GIS if you want a full power solution, though they are more complex and focused on larger scale data-sets in a way that can make them a bit of a pain when dealing with global data sets at times.
