Excellent piece of news! I hope I'll be able to have a proper Internet
access then (I've moved ino another flat, but my Internet provider is
kind of sloppy...) to update my modifications and send the appropriate
patch.

 But, I think you are facing some unique

Indeed, it's mainly because I want to test my futur patch properly :|

When finding the .ipython folder for the furl file. It's not in the
$HOME folder of the nodes, but in the $HOME folder of the controller.
Fo the moment, I copy the furl file on the fly, but this isn't a
viable approach :|

OK, I'll test this.

I hope I'll be able to find the time to figure it out (and the
Internet access as well :|)
