Since no one knows who you and your friends are, you could easily be the NSA, right? It seems to me that when launching a security/privacy service you should make an effort to explain why people should trust you.

I don't know if you're soliciting advice or not; but a privacy policy probably wouldn't be a terrible idea.

Hope you don't mind my asking but how did you come up with a figure of $5 a month and how much bandwidth do you anticipate each user will use?
