Another tool to look at is vpncloud (https://github.com/dswd/vpncloud). It also builds a mesh network over UDP. Key setup is a bit easier, static keys are only used for authentication. Encryption keys are dynamically generated and replaced on a schedule.

I combine it with an ansible script to push out the (minimal) configuration to end nodes.

P.S. It is a Rust program, I compile it as a static binary, so my ansible script can push the binary out to any Linux distribution (that is x86_64) and it will run.
