After years of discussions, I am glad to see this topic has finally been submitted for SEC review. Having more then one player in the space fosters competition and breeds innovation. It also allows the free market to dictate fair pricing and eliminates the single point of dependency. I look forward to the SEC approval on this as it promotes good business and additional choice for market participants.
