Disclaimer: I'm one of the principal forces behind this change, and am on the Marketing team at VMware/'Virtzilla'.
It's more than just vCloud Hybrid Service, but it includes all our VSPP partners who offer VMware based services. Our ecosystem is greater than just our service offering, and our value channel has the need for the same interoperability that we deliver with vCloud Hybrid Service, so it just made sense.
Thanks for sharing the good news, we're really excited with the possibilities this technology introduces!
