Ah yes, it will certainly be some work. I was under the impression that HDF5 has already paved the way for us, but perhaps that judgement is a little optimistic. I wish there was some sort of generic framework for dealing with this since I have a couple of other projects for which it would make sense to have them in serial and parallel.
Anyhow. Although I'm not firm enough in patching the build system, I'd be more than happy to help out getting netcdf ready for parallel.
