Great, this looks very helpful using tools such as cssh. I find it annoying to prefix commands with sudo and add sudo -i in my bashrc. I will explicitly drop root when building software, etc. Using sudo has never prevented me from making a mistake and auditd handles logging as opposed to syslog
And I just settled on never using this. Why would you pick GPL v3... Shell scripts are the last place I want to argue with the company lawyer about.
I'd like to politely suggest you consider changing the license before you accept contributions. The smaller the tool and the more modularity it has within a software stack (shell script helpers are extremely modular) the more appropriate it is to license it something towards the MIT license end of the strong - weak copyleft spectrum.
