FlightAware provides terrific accessibility to our PiAware devices. The only shortcoming is that we can only use Skyview when are are on the same local network. I was toying with the idea of trying to punch through an obscure port on my router so I could reach my Skyview externally. Or setting up a vpn or ssh tunnel. And then I thought… what if the FlightAware “My ADS-B” personal user page actually included safe and private access to the PiAware, which was running the other end of some kind of VPN or ssh or tunnel software?
