Mini tangent: Could someone explain to me why Qubes is used for security, when (from what I understand) Jails on BSD is significantly more robust/safe/has a much smaller exposed area? Is it just "everyone's using linux already; here's a safer linux"?
Qubes uses VMs, Jails use a shared kernel. So I wouldn’t say Jails are safer nor that they have a smaller exposed area with regard to host isolation than VMs.
Qubes can be viewed as a Xen distribution, rather than a Linux distribution [1]. You may find the Qubes FAQ a good starting point (I'm reading it now because of your question, so thanks).
