I agree, this is a good discussion for the node meeting tomorrow.

ESXi has their own package format, VIB. They provide tools for third parties to build and sign VIBs, and then they allow for loading of these packages onto ESXi instances. If you look at their stateless model, they take the VIBs, package those into images at the vSphere level, and allow hosts to boot the compiled images. This allows for third party drivers, CIM providers, etc. to be loaded onto ESXi hosts, both stateful and stateless. This is something that may be desirable for the node as well, to allow for the same sort of third party packages to be loaded.
