Hi Loïc

Wow that's awesome news, and thank you for the documentation! :)

One question remains: In
you mention that it isn't possible to listen on well known ports, why
this limitation? If you start the node under a privileged user, or use
tools such as privbind or authbind it shouldn't be a problem at all,
