It does support vCloud, but uses the IAC 3.1 Cloud Model, so although it creates a vApp, there is always 1:1 vApp:VM.
We would love to have someone extend the Multi-Cloud content to have 1:m vApp:VM. All the pieces are there; they just need to be assembled as part of IAC w/MC. (PS. We are working on another project to extend the cloud model to cover PaaS use cases with server stacks, which makes the need for vApps go away).
