zyGrbib is useful not only to download and display GFS forecast, but it is also a very useful program to display and analyze grib data from other sources. For example, this in an animation of the sea current in the Gibraltar Strait done using zyGrib with data from MyOcean:

It is possible to find free and very interesting weather data in the internet in format Grib2 instead of Grib1. For example,
http://www.opc.ncep.noaa.gov/opc_gridded_marine.php
So, my suggestion is to add support for Grib2 format in such a way that zyGrib could be used to display those kind of files.
Thanks a lot,
