If I'm remembering correctly, there was some extra validation and testing that FedEx wanted to do before they would give me a production URL. Since I didn't know what it was, I didn't put it into the module. Also, since we're not using FedEx in house, it stopped being a priority.

If anybody is willing to figure out how to get this working, I think that would be awesome. I just have too much other stuff to do right now.
