Wow, what an inventive use of the IDV.

We are totally reworking the netCDF underpinnings for point data in
the IDV for the next release, so your question is timely.

What do you want to do with these other dimensions?  You may want to
look at the proposed convention for station data in the new netCDF
package:

http://my.unidata.ucar.edu/content/software/netcdf-java/formats/UnidataObsConvention.html

to see if that would suit your needs.  This is still in development and
we would appreciate your input on this.

Note that this new format will not work with the currently released
IDV (1.2b2), but will work in the next release.

I've cc'd the developers of this proposed format in case they
have any suggestions.
