GEMPAK can use the Python DAF to display data from a remote EDEX server.  Make 
sure you install the package,

https://github.com/Unidata/python-awips
http://python-awips.readthedocs.io

GEMPAK will need to be built against Python... the env vars needed for the 
source build are included at the end of Gemenviron.profile and building GEMPAK 
needs only the same "make everything" command as a normal build.

Then look at the XMl files in $GEMTBL/data-access/ and their corresponding 
alias entries in datatype.tbl which start with "A2":
