You've got one more week. ;-)

Which fields do plot?  Do any 3D fields plot?

In general, accessing grib, GEMPAK and (to a lesser degree) netCDF via http 
will be slow and your results may vary.  You would be better off setting up a 
RAMADDA server to host these and use the OPeNDAP access built in to it.
