Update data

Hans,
* using shapefiles, this isn't possible with mapserver (or at least I
don't think so, someone correct me if not)
* if you're using postgis, you could implement this with some server
side scripting, with or without some help from the mapscript functions

I think the way to go for your case is geoserver and its wfs-t functionality:
