I've been using spiped in production now for a few years, ever since the initial announcement here. I tunnel Zabbix health monitoring communications to and from the server. I don't have to worry about setting up users, and each node 'config' is only 1 shared keyfile. If a node is compromised, I can cut it off with one move ( changing the shared key )
