I store server configs in SVN (in a mini fs layout) with a copy checked out 
somewhere on the boxes, then you can diff/update the local copy and commit to 
the SVN server when you make a change. With this method to copy a config 
between server you'll need to commit it to SVN first on one host and update 
the checked out copy on another, this gives you a record of what changes are 
made and by who.

You could use a simple text file which states the config file and the command 
to restart/reload the associated process, then have a script to run through 
this, check for changes (md5sum/diff) and run the command. 

This may work for you.
