Btw. today GeoTools/GeoServer guys published a blog post about improving raster reprojection speed: http://geo-solutions.blogspot.com/2011/01/developers-corner-improving.html There's also a link to a more verbose 35-page tech report on this matter. From a brief look it's the same approach as used in MapServer.
