So rather than securing connections at the os level, we re-invent the network stack past layer 3. First you bring your own crypto, then create a whole new virtual network stack, then create connections. Or do what Google does and bring your own crypto, then bring your own layer 5-7 routing and transport on the server. These are "interoperable" if 1) your users download an extra app, or 2) your server implements custom app-specific solutions.
