Instead of using teleport's pay services to do this, how is this any different really from having something out in the world on a lte connection initiate an openvpn connection back to your own server, and maintain a persistent tunnel to its new tun0 interface, and then ssh to that? The cellular network load of periodic openvpn keepalives is very low.
There isn't any difference, of course -- other than perhaps giving control of the keys to the kingdom to some Silicon Valley startup!
I was deploying cellular devices (from Digi and, later, Opengear) at power substations in rural areas to tunnel RS-232 serial in IP over IPSec over cellular connections a decade or more ago -- and it's not like I was the first one to do it.
Teleport is a YC company, though, which is probably the biggest reason so much of their marketing^Wblog posts show up here.
Running Kubernetes on a self driving car/truck? SSH-ing into a self driving truck? Both of those statements cause me to shudder at the thought.
