Being able to do this would be very cool, much easier to script daily
(or weekly) updates if you can do something like:

TODAY=`date ...`
YESTERDAY=`date ...`

cd /my/planet/download/directory/

wget http://planet.openstreetmap.org/planet-${YESTERDAY}-${TODAY}.osm.bz2

planetpatch ./* | osm2pgsql -
