Another possibility is osh (http://geophile.com/osh). You could do something
like this:

    osh @your_cluster [ f 'your_function' ] $

- your_cluster: logical name for the cluster.
- your_function: A python function you write to be run on each host.
- $: Prints information from each node as a python tuple.

You could, instead of printing with $, pipe the result to other
osh commands to further process the tuples containing information
from each host.

I wouldn't recommend this if the hosts are Windows since osh hasn't
been tested on Windows.
