The SSH Provisioning step seems to take a while sometimes, and it would be really nice to see "what" its doing. I envision an interface similar to the way that rhgb (red hat graphical boot?) allows you to see a "scrollbar" by default, or "gory details"

For the web, it might have to be in a popup window or modal dialog or something (not a web guy, sorry) ;)

It looks like its already refreshing status once per second anyhow, so maybe it can request detail or "debug" output (which might be a hint on how to get the output)?
