Let me first address the free advertisement comment from Likewhoa and then I will get to the real questions in more details.
I am more that happy for your customers. Pipecrew seems to be very happy with your services. I don't know how long he is hosted with you but I bet he just learned today that you provide anti-hotlinking protection

Otherwise I am sure he would have mention it earlier.
I went through all of the pages on your site, but I could not find any information about the ability for your customers to save money on their bandwidth bills with anti-hotlinking protection. I wonder why?
