Anyone successful with creating a template for vCloud?

We rely on vCloud. I saw someone ask about vCloud recently on these forums and they were linked to - but it looks like it’s incomplete. Anyone have any success at integrating Packer and vCloud?

I myself am going to be trying to take the output from a Packer + vSphere run (produced items were .vmdk, .ovf, and .mf) and try to use PowerCLI to get it into vCloud programmatically. Not sure what my success will be.
