Hi Adam,

Issuing the command "make programs_gf" in $NAWIPS will build versions of 
several programs that are linked directly to the device drivers and eliminates 
the gplt/message queue interface.  Using gpmap_gf rather than gpmap, for 
example, should speed up image creation time.

As for how useful GEMPAK would be for your purposes, invoking scripts from a 
client-side interface is really not going to be as quick and fluid as you will 
want, I'm sorry to say.  Much easier to generate products at certain time 
intervals via cron and update/upload to the website as you go.
