I would say that clusterssh fits that criteria most directly. Writing a shell script to execute a series of commands on remote systems wasn't something he asked for. There's your 'reason.' As far as ssh keys and such being set up, that's really out of the scope of his question. I've used clusterssh to edit the same file (vipw, for instance) on 30+ hosts at the same time. It gets a bit cumbersome, but at least I can see what's going on in each instance, without writing a complicated script to do the same.
