I think it's time we give up on the idea of communicating privately over a centralized network. Wiretapping was invented only a few years after the invention of the telephone[1]. It won't be stopped by technology and certainly not by legislation. People need to get used treating the Internet as a public space: cover your mouth when you cough, don't pick your nose in public and don't communicate sensitive information over the Internet.
The next big thing (hopefully soon) will be communication through a decentralized, infrastructure-less device.
