There's a very simple solution to this. Use strong encryption and obscure or otherwise hide the private keys. We're trying to develop a future conscious messaging client: http://emp.jar.st/ http://emp.jar.st/ Is it NSA proof? Probably not, but it will thwart most prying eyes, including LEOs. The idea isn't to make data impossible to get to (this in and of itself is impossible). But rather to make it exceptionally expensive to get to, this forces the people with prying eyes to be much more selective.
