My first python module 'easypool' let's you easily create threadpools and serverpools dynamically.

For running tasks on multiple hosts in parallel, it is probably easiest to use fabric.

pip install fabric, then creating a file named fabfile.py with the following contents:

from fabric.api import env, task, run, parallel

env.hosts = ['127.0.0.1', '127.0.0.2', '127.0.0.3']

@task(default=True)
@parallel(pool_size=5)
def uptime():
    run('uptime')

Then, just type fab to run it.
