Virtualization places a guest system into a separate security domain, typically with fewer privileges than software running directly on the host. Increasingly, there is interest in creating multiple security domains within a single virtualized system as well. CPU vendors (and software vendors too) are implementing solutions; each of which, of course, is different from all of the others. KVM planes, currently under development by Jörg Rödel, Paolo Bonzini, and others in the KVM community, is an attempt to provide an abstraction layer that makes all of these features available on Linux systems; it is not a small task.

GNOME contributor Tobias Bernard has published a blog post that details some of the design team's ideas for the GNOME Shell over the long term:

Some of these we have relatively complete plans for, others are more vague ideas that need more research and prototyping. As always, getting things like these implemented depends on developer capacity and interest (and sometimes funding).

While each of these ideas may require additional discussion, prototyping, and testing, we (the design team) have collected them all together here to share our longer-term vision and to give each idea more visibility.
