Hi Ian,

Sorry to have taken so  long to respond to your question:
> Are there any plans to enable the HDF5 scaleoffset filter to be called
> from netcdf interface or indeed any other plans regarding lossy packing
> within netcdf.

There is a rather old Jira ticket on this:

  https://www.unidata.ucar.edu/jira/browse/NCF-39

which seems to be assigned to me.  So it's on my list, but I don't think
we were considering using the HDF5 scaleoffset filter.  That might be a
good way to implement it, although we were looking for something that 
would work for netCDF-3 as well as netCDF-4, and in that case, the HDF5
filter might not be available.

We've also discussed supporting GRIB2 compression or wavelet compression,
both of which are lossy, but we're currently a little short or resources
for such undertakings.  There's hope however: we just hired a new
developer! :-)
