Walsh: Secure Virtualization Using SELinux (sVirt)

So... obligatory Canonical question.

Is Canonical still positioning AppArmor as the default MAC option in its Eucalyptus based Ubuntu Entreprise Cloud Architecture product? Is there an equivalent effort underway to use AppArmor to provide a similar level of protection to what SVirt offers? Or has Canonical essentially punted on the issue of security in the cloud while pushing its server product.
