I have decided that I would like to create a TurnKey appliance that provides the minimal host OS to run VirtualBox VMs "locally". Like a LiveCD that allows running Vbox VMs without moding the underlying physical box. This should also be installable to bare metal when that is an option.
Why VirtualBox? Because my use case requires running Windows games that require DirectX 3D acceleration and no licensing fee for the Host platform.
I'm probably going to set up some kind of "project" to make my work available and get some help. Should I do this on Launchpad? I believe that is closest to TurnKey's own process.
