There will need to be a fair amount of device infrastructure programming done to get there. Things like the Pyra's Debian OS will need to be running a program to default to the 4G data connection, but only when a known WiFi network is not in range, but only if a USB Ethernet dongle is not plugged in. To do the VM trick as above, it would then need a software bridge to link whatever network that is that it can connect to the VM manager, which still needs to be developed to even work with the platform, which does not have 3d drivers yet to even plug any of that into... So, I'm not expecting to be able to run my dream of 2 Android VMs inside the Debian host for a long long time. Someone please surprise me on this.
