Looks interesting. Reminds me of a pet peeve. Apple and Microsoft should have gotten together a long time ago and built secure email and messaging into every copy of their OS so people would use secure communications by default. I'm thinking they could have leveraged PGP, or somesuch. Instead, they both seem to act like the government's bitches. I've never quite heard why this is impractical.
On the other hand, I've never delved into PGP, etc., so maybe there are real issues, other than the political ones.
To the point on this, though...seems sorta like saying "Here we are, the people who don't want you knowing what we're communicating; come and get us."
