Evening all. By the way, if you enjoy networking and find it interesting (as I do) then don't mind if I tell you about #yggdrasil which runs a VPN on the 200/7 IPv6 subnet. Pretty darn fun and cool. Like cjdns but faster and with a different network topology. A spanning tree (but with shortcuts).
Are you saying there are apps or asking if there are? If it is the former, then where as I am not aware of any. If the latter well the team hasn't made one yet.
