OK, fine, I've done it myself.
This program will monitor a folder/directory for new SE4 savegames, and prompt you to run SE4 with any samegames that appear.
If you click yes to the query, SE4 will automatically be run, loading the savegame, and using your player # and password.
This only works under 1.41 or higher, so I had quite a time testing it
. (I've got 1.35 installed, since it dosen't crash under WinME)
