Qubes: security by virtualization

This is interesting. I like that people are looking in to things like this. As just an average user I would be interested in seeing, in the not too distant future, a system where isolation brings me network transparency for free (or cheap). Ideally I'd like to be able to suspend an application or set of applications (ie, a workspace) on one system, transfer it to another host, and restore it with its state remaining the same. This is possible today at the VM level but requires a complete, heavy OS instance for each workspace/application. The idea is to achieve app-bundle-like ability to transfer programs on a network without requiring one directory per app and to also permit me to care even less what computer I'm actually sitting at.
