I don't know any shipper whose first instinct is to start a complaint process or use a regulatory process. These are business people, and their preference is always to try to negotiate something.
Part of the usefulness of these remedies is that they provide, as David mentioned earlier, a kind of backstop in an environment where you don't have the option of saying, “Fine, I don't want to deal with you. I don't like your terms. I'm going to go to your competitor.” That doesn't exist, or it only exists for a small portion of your traffic. The fact that this is out there, that there is a remedy and that it is usable, performs that same function for a lot of shippers. It's as important for that negotiating function that the remedy work and be usable as it is for somebody actually wanting to ship traffic under an interswitching order.
