Daige no, functionaly WAU and the File site are the SAME exact version.
WAU is an Installer, where as the File Site is ment more for single addon distribution. WAU will "Unpack" the file making them "Load On ?Damand". some times you have problems ... sometimes you don't
for the most part LoD addons have issues with What sequence they load in.
