I believe IPv6 provides a start for what is necessary to solve Step 2. IPSec is part of the protocol so these connections can be trusted. Also no NAT issues so connecting directly between trusted 'plugs' may be simpler than with IPv4. May need to start with a mesh network over a mix of paths that you own and paths that you may not. I have no real world experience implementing IPv6, just been looking into it lately.
