Hello Klokan, Thanks for encouraging me! And congratulations for your excellent job with gdal2tiles. It really saved me from a lot of unproductive hours... It would be great to help you with WMTS implementation, or work with PNG driver, or with WKT Raster driver. I'm going to apply for the three

Jorge, I am glad you are interested in the PNG driver, which I suggested as a project for Summer of Code... It would be really great to have this in GDAL and I guess more projects will profit from this... I am going to assist as much as I can, whether in gsoc program timeframe or even otherwise.
