We've already released a PaaS built ontop of Kubernetes at Red Hat, with the upstream named OpenShift Origin and the supported version named OpenShift Container Platform (https://www.openshift.com/container-platform/).
Our developers contribute a ton of work to the Kubernetes project, and pretty much everything that works on Kubernetes will also work on OpenShift. We do have some security settings by default that are more restrictive (like no containers running as root) but that can be easily modified to be more permissive.
