Hi Jennifer,

> Is NcML supported by the netCDF4.1.1 library?

Only in the sense that netCDF-4.1.1 (and the new release netCDF-4.1.2) 
both support client access to OPeNDAP servers, such as Unidata's TDS, and
the TDS supports NcML.  So if you have files on your server aggregated
via NcML, for example, you could access data from the aggregation from
a C or Fortran client program using netCDF-4.1.1 or -4.1.2, opening the
aggregation with a URL rather than a file name.

There is currently no support for reading netCDF data from local NcML
files, without contacting a server that supports NcML.  Such a server
could run on the same host as a client program, and in that way you
could access data through NcML, but that's a fairly heavyweight way
to get access through NcML ...

We're considering the possibility of something like a TDS-lite that
would provide TDS services on the local file system with little or no
configuration, but it would still require a query to the server to 
access local data.

I'm Cc:ing Dennis Heimbigner in case he has anything to add.
