Yes, local events and pandora's boxes are essentially the same. LE works for pandora's boxes (which is said in ERM help) and PA should work for local events (but mostly wouldn't, because there is a critical bug; I'll try to update today). I found out about LE when I was already implementing PA, so it was too late to change something and PA works differently anyway (so it can not be made into a replacement for LE). Aslo PA doesn't have the restrictions of LE.
