In the end my solution was to download, compile an install the latest version of cloud9SDK.
First, all this process was done with a Node.js version 6 and a clean distribution for the BeagleBone Black (BBB).
#Compile the cloud9 application
###Clone the Cloud9 repository (check if this is the last version):
git clone git://github.com/c9/core.git cloud9
Make sure all the installation scripts run by this last command run and finish successfully!
###Launch the cloud9 server! Only listen to incoming petitions to 192.168.7.2
node server.js --listen 192.168.7.2 -p 3000 -w /your/project/work/dir -a :
Connect to http://192.168.7.2:3000 to start developing.
###The cloud9 server can be set to be up and running with systemctl as in the original distribution.
You will need to edit:
Performing that configuration can be tricky, as you need to update and fix the connect-architect node module, so perhaps it is just enough for you to connect to the BBB through a SSH connection and then init the process from the console:
systemctl start cloud9.service
systemctl --system daemon-reload
Hope these lines help anyone in the same situation.
