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.
