I'd be interested to know how large the market for that actually is. It's clear within the HN world that some people are upset about the NSA and other organizations being able to easily access their data, but how large is the market for people who are willing to pay to not have that happen? I'm concerned that it's actually pretty small.
There's also a bit of a catch-22: if you start a company that provides secure email (for example) then I'm not going to pay you for it because I don't believe that you can provide me with secure email. The only way for that to happen is if I use GPG or similar myself and take total control.
So, I'd be concerned that the very people who might worry about this stuff are the very people who aren't going to pay you for the service.
