Hey Ettore!
It is not recommended to use WPN-XM as a production server (Oct 2014)!
Our focus is clearly on providing a stable development stack, with all the tools working right out-of-the-box.
This issue (WPN-XM as a production server) is currently not on our roadmap
If you are really interested in making it production "safe",
then please feel invited to open an issue on GitHub and help us making WPN-XM better by contributing.
The faster we will get the stack working in production.
Regards, Jens
