In general, you are *much* better off dealing with clusters -- and even
heterogeneous networks -- using a declarative tool like puppet or
cfengine.  It costs some manhours to set up, but IME you end up with a
more robust setup than just blindly running the same command on a dozen
or a hundred hosts at once.
