The idea of having it physically portable on a thumb drive is neat, never thought of that. I just use a vagrant script with a base box that has puppet so I can recreate a VM configured exactly how I want by issuing a single command (vagrant and puppet scripts are on a git server so could be pulled on other machines). I would lose state obviously on a new machine though. I guess one could use a cloud file service to store the VM and state(s) to avoid losing the state via a single point of failure (local physical media of some sort).
