Take a look at cfengine: http://www.cfengine.org/  (don't mind the ugly
web page).
This program is used at many very large installations to make sure every
machine
has the right configuration files. Clients query a master at each
interval to check
if their configuration has changed. Thus instead of having to log on to
each machines
to change the configs (which is error prone, not to mention long and
painfull), 
you simply change the file on the master and let it distribute itself.

It's relatively easy to setup and works very well.

Cheers,

David
