Hi, > does anyone know whether a shape-layer can be transformed on the fly > with using the definition of an NTv2 file
yes, you just need no create two custom CRSs. Assuming that your NTv2 grid file is for a transformation from crs A to crs B than the two custom CRSs must be defined as Ac = A +nadgrids=yourfile.gsb +wktext and Bc = B +towgs84=0,0,0 +wktext and then set Ac as crs for your layers and Bc as crs for your project. A plugin is under development to make (much) easier to handle NTv2 grids and transformations under QGIS.
