Description of problem: you must currently know to use `rhc ssh <app> --gears 'tail -f jbosseap/logs/*';` in order to tail all the logs of all gears at once. This is not the most intuitive, though it does work well. http://ocpsoft.org/jboss/openshift-pro-tip-scaling-tail-server-logs-on-all-gears-of-your-app-at-once/ It would be far simpler to have an `rhc tail-all <app>` command. Cheers!
Started this here https://github.com/openshift/rhc/pull/465 - needs net-ssh-multi packaged (in progress) and test cases to work.
