Howdy Dave!

I hope you understand that netcdf-4 is very experimental. In
particular, don't expect any files to be readable to future versions
of netcdf-4. The alpha releases show how the API works, but use
special constructs in the output file to compensate for missing HDF5
features. These features are being added to HDF5, culminating in the
1.8.0 release (due out in January).

So our netcdf-4 HDF5 files will not be stable until after that. When
we release the beta, we expect the format will be stable. When using
alphas, be aware that you should not create data archives.

The alpha release you're using has known bugs with unlimited
dimensions. The next alpha release fixes these problems, and adds a
lot of testing of unlimited dimensions. I expect the next alpha
release will come out next week.

So try again next week, and let me know if it still doesn't work.
