roslaunch api - start/stop nodes on a remote machine

edit

I am trying to write a python script using the roslaunch python API found on http://docs.ros.org.ros.informatik.un... . If I run this code on machine2 it always starts the node local on machine2 even though I specified machine1. Everything works well when I do the same thing within a launch file specifying the machine1 in a machine tag.

What am I missing out? Has anybody ever used the roslaunch API for launching nodes remote?

master = roslaunch.core.Master(type_='rosmaster', uri='http://192.168.139.200:11311')

uuid = roslaunch.rlutil.get_or_generate_uuid(None, False)
roslaunch.configure_logging(uuid)
name = 'image_view_abc'
package = 'image_view'
type = 'image_view'

machine_1 = roslaunch.core.Machine(name='machine1', address='http://192.168.139.200', env_loader='/opt/ros/indigo/env.sh', user='account')

node = roslaunch.core.Node(name=name, package=package, node_type=type, machine_name='machine1')
node.machine = machine_1

launch = roslaunch.scriptapi.ROSLaunch()
launch.start()
process = launch.launch(node)
