I'm a bit disappointed this is just accessing a service you expose as a hidden service, not a p2p NAT traversal service that happens to perform a handshake on Tor. IPFS p2p is also usable for that kind of thing (and will perform NAT traversal if possible), though Tor and i2p are probably better fits if traffic needs to be relayed. I also used yggdrasil, but you need to maintain at least a static peer. After that though, using IPv6 addresses is nice. cjdns and hyperbora work the same.
