Two is too many.  IIRC, you're capable of a bit of scripting.

getgpxroute austin,tx "1600 pennsylvania avenue, washington, dc"

The idea is simple and can be implement in about any OS and/or scripting
environment.  My getgpxroute looks like:

#!/bin/sh

while [ $# -ge 2 ];
do
  FROM=3D$1
  TO=3D$2
#  echo "Getting $FROM -> $TO "
  wget -O - \
    "http://maps.google.com/maps?q=3D$FROM to $TO&output=3Djs" > /tmp/gpx=
r.$#
  CMD=3D"$CMD -f /tmp/gpxr.$#"
  shift
done

gpsbabel -i google $CMD  -x simplify,count=3D250 -o gpx -F - | \
  egrep -v '</?rte>'  | \
  sed -e 's/<bounds.*>/<rte>/' -e 's#</gpx>#</rte></gpx>#' | \
  gpsbabel -i gpx -f - -x simplify,count=3D450 -o gpx,gpxver=3D1.1 -F -


This is actually more complicated than most such scripts becuase it's all=
ows
for multiple stops to be passed on the command line but the ultimate cons=
umer
of this data gets all confused about the multiple segments that we genera=
ted
above.   If the reader was smarter and you didn't need to be able to intr=
oduce
interim stops it could be a one-liner.
