Has anyone mentioned cluster ssh yet? Depending on your scale, cluster
ssh and a "really big screen" may be a suitable way to manage N servers
and do things like apply updates or make identical changes to all at once
(or in groups). It also gives you the flexibility to apply commands to
all or single out a system and do things just in the one window, then to
back to talking to all.
