I've long wondered if something like this could replace more traditional VDI. Of course, it would depend on being able to use Linux as the desktop. I imagined having Guacamole spin up a desktop container with a directory mounted into it for the user's homedir. The OS is ephemeral but not the user's data. It would never need to persist like the home directory. Need a different base OS? Provide other images that could be selected between. Update time? Upgrade the packages in the image and they roll out as people log out. Resource usage would be lower (than VM VDI setups) because the containers would disappear after they logged out. I never really got past the idea, but this reminded me.
