Yes, I do this in some of my programs for exactly the reasons you cite.  I
install the CDL files in a known place, and when new data comes in the
program writes it to the appropriate netCDF file if the file already exists
or first creates the netCDF file using a system() call that invokes ncgen
with the appropriate CDL file if the netCDF file doesn't exist yet.  This
seems to work fine.
