Have you considered just using live Linux? Buy some 16gb USB3 sticks in bulk, and flash it with a distro that runs well off the drive. That way you don't have to clean up after each session too, you can just shut off the computer and it will go back to a regular Windows PC.

Since we already have computers this seems very attractive. Thank you for the suggestion, I'm pursuing it.
