Lynton,

That's great to hear!  I considered asking you about the status of that 
effort, but didn't want to appear to be pressuring you for results when
this is a volunteer contribution to the netCDF community :-).  I would be
happy to incorporate your results into the netCDF distribution when it's
ready.  We have a beta version of netCDF 4.1 that would be a good place
to deploy a test version of the new C++ API implementation.

That's a philosophy I agree with whole-heartedly.  Keeping extra copies of 
the state of things in the C++ layer is undesirable for exactly the reason 
you have stated.

No, we have been telling users who ask about it that the netCDF-4 interface
is "under development" and we have made no changes to the partial 
implementation that's in the current distribution.

Thanks again for your valuable work on a new C++ API.
