I managed to setup port forwarding in my wifi router. I started ftp server on my laptop and was able to access ftp from a separate public ip pointed to wan interface of my router.
So the networking part is possible. I will enable the port forwarding when I decide on the port number.
When I turn my attention back to the google document
