We've already had this working, the GATU server relay is ​a web server. The 127.0.0.1:8080 server can be accessed at your local IP address behind your router at (for example) 192.168.1.103:8080, from there it is a (relatively) simple step to forward a port from your router to your internal IP address (ie 192.168.1.XXX) at port 8080 from any external port you'd like (ie 60000) and then anyone with your outside IP address and forwarded port should be able to see the GATU status page served from your Kerbal gaming rig. Keep in mind there is presently no authentication, so anyone that sees your port/knows your port/ip will be able to see your Kerbal flight info. Mission control can absolutely be off site, and its a blast!
