Thanks for your valuable comments. If I understand you correctly I can
either access the overviews in the tiles by hand crafting vrt files
for each overview level or sacrifice disk space and generate external
overviews using your gdalwarp trick .
A comment from Frank  back in 2005 confuses me. He mentioned
VRTSourcedRasterBand in the context of overviews in the tiles, but I
only know of VRTRasterBand .
Thank you for any further comments,
