The lavabit case highlights something interesting that we need. We need that not only individuals have privacy, but that businesses have privacy of who their users are. The same way we provide anonymity to users through centralized means, is there not a way to provide a way for service provider to have a sufficient level of opaqueness of who their customers are. You can't subpeona Service Provider A if you don't know whether Person of Interest X is using the services of A, B, C, or D, etc.
Not exactly the same. The company can know that I am a customer. What I'm talking about is a third party not knowing that I am a customer of the company.
