We intend to support all CF projections, but only add them when we have a valid example. Are you reprojecting these files as you change the projection, or only changing the projection info? IE, what projection do you want to use? Docs on what we support are at: http://www.unidata.ucar.edu/software/netcdf-java/reference/StandardCoordinateTransforms.html please let me know if you have an example that doesnt work according to the docs.
