Possibility of having other model grib files

[WxEyes]

I was wondering if it could be possible to have grib data for other numerical weather prediction models available? Models I have in mind are the NAM and the RAP model both from NCEP; also any possibility of UKMET GRIBs too. The NCEP webserver has this model (coarse grid or LORES GRIB data on it too).

Thank you in advance..

BTW - Very GOOD program.
