Hi,

First, this is my code snippet : https://gist.github.com/28d47535e9dba220e120

For the moment, the SshParticipant only put something in the workitem
and the ResultParticipant print it.

As you can see, I try to use multiple engines with a Redis storage to
launch the main process and a subprocess. My goal is to do that in a
distributed way with possibly hundreds or thousands of hosts on a
computing grid.

So far, I got this error message :

Thank you in advance for any help, I'm completely stuck on that for 2
weeks now.
