Take a look at cfengine. You can maintain system state better than just
pushing out mistakes, you can pull changes instead of pushing changes from
each node, and the syntax (AlthoughRatherSelfDocumenting) is straight
forward. You can also do it through a des encrypted transfere.

Also, prsh is handy. It beats writing 'for' and 'foreach' shell scripts.

Or you can use rsync (ssh -e rync). 

The world is your oyster.
