Python subprocess.popen over network

Python subprocess.popen is easy as pie on local machine, but is it possible to call it over a network?

Example, say I have 3 PCs, one is called workstation-pc, the others are called node1-pc and node2-pc...

Is it possible to call a process on, say, node1-pc, from workstation-pc, preferably without having to run special server software on node1-pc?

In any case, many thanks for any response!

Gilles

EDIT Forgot to mention that I am using Python 3

I would recommend the use of either:

Example with Fabric:

from fabric.api import env, run

env.hosts = ['host1', 'host2']

def mytask():
    run('ls /var/www')

Fabric is probably the way to go, however, there is nothing to stop you executing remote commands via ssh in *nix environments.

import subprocess
p = subprocess.Popen(['ssh', 'node1-pc', 'ls', '-ltr', '/etc'], stdout=subprocess.PIPE)
out, err = p.communicate()

out will contain the stdout of the remote process.
