Add `fastd` or `vpncloud` to build full-mesh for `tun` and `tap` tunnels.
Both solutions are decentralized and don't use a client/server model.

VpnCloud features the following functionality:
Automatic peer-to-peer meshing, no central servers
Automatic reconnecting when connections are lost
Connecting hundreds of nodes with the VPN
High throughput and low additional latency (see performance page)
Creating virtual network interfaces based on Ethernet (TAP) and IP (TUN)
Strong end-to-end encryption using Curve25519 key pairs and AES methods
Easy to use interactive wizard
Support for different forwarding/routing behaviors (Hub, Switch, Router)
NAT and firewall traversal using hole punching
Automatic port forwarding via UPnP
Websocket proxy mode for restrictive environments
Support for tunneled VLans (TAP devices)
Support for publishing beacons to help nodes find each others
Support for statsd monitoring
Low memory footprint
Single binary, no dependencies, no kernel module
