Hi. Since you yourself create the KML format the format and projection
options passed to the vector layer are useless. To make the KML format
do the re-projection try:
var format = new OpenLayers.Format.KML({
internalProjection: new OpenLayers.Projection("ESPG:900913"),
externalProjection: new OpenLayers.Projection("ESPG:4326")
});
