[arm-allstar] Radioless Node

[Robert Prybyzerski]

I created a Hub on a Pi so I could park my portable node there.  The portable node is using the Freedom Pop hotspot and cannot accept incoming connections.  
This way if someone needs to contact me they just connect to my hub.  I also park some of my other nodes there to create my own linked setup.
