I am pretty confident as well that at least distribution of the ECW dll is not permitted. It's probably even worst than that, as I am not sure that even linking QGIS-GDAL-ECW is legally doable. A clear statement would need some thorough investigation though. Frank probably has some further thought on this point. > The "old" read-write ECW libs that are typically used on linux can > supposedly be distributed with GPL software, so I think it would make > sense to use them also on Windows (especially since they are read-write). Right, but no idea of the technical difficulty there.
