This plugin does have some nice features. Although I was wondering if you guys were going to implement authentication using ssh keys. I noticed that you did implement passwords and sshpassphrases but no keys. I keep getting errors reject host key: "servername". In the source it looks as if this has not been implemented. Although I'm not much of a coder and this is simply to see if this is in your road-map or if I'm just way off and there is a way to do this.
