Jan,
I will note that the NTv2 file format used for grid shifts in PROJ.4 is now
supported as a raster format by GDAL. So if you can get your grid shift
information into a suitable form, you can translate it to NTv2 with GDAL.
Hmm, I really need to provide more information on this.
You can also use GDAL based applications to examine NTv2 files.
Best regards,
