@jgoerzen I ran cjdns on several of my machines, and a cjdns service on a VPS to provide an "infrastructure" node, for this very reason for a number of years.
I have since abandoned that for practical reasons (I was not keeping up with the network news, and it was changing rather fast at the time), but in general I am in support of this kind of effort.
It's hard to trust a service like this on an important machine, though.
