No, as get_NWSdata just snags the weather alert shapefiles from NWS,
not from Gerry's server.

The weather alerts which we receive over INET or RF are short
single-line APRS messages which specify zones to light up.  Those
zones are then pulled from the previously-loaded fairly static
Shapefiles that we get from NWS.

Nope.

Yea, but those contain either lists of zones to light up that are in
the NWS Shapefiles, or they contain polygons that get drawn in
Xastir itself (nothing to do with Shapefiles in this last case).
