Hi, For those interested I've tested out the vCloud compute driver (API v1.5) on VMware vCloud Service Evaluation Beta (https://vcloudservice.vmware.com/).
The only quirk so far is external NAT routed instance IPs will need another API call currently not used in the libcloud driver: http://pubs.vmware.com/vcloud-api-1/wwhelp/wwhimpl/js/html/wwhelp.htm#context=api&file=vCloud_API_Guide_Admin.8.7.html#1039433 Originally the vCloud v1.5 compute driver update was intended to facilitate private cloud (test lab setups), however it's good to see it working well with a public provider.
