Do you know products that can be use to deliver some statistics to vcloud director organization owner about the behavior of their virtual machines (and org vDC) like they are shown within vcenter (cpu - memory - ballooning - IOPS - ...) ?
VMware vCenter Chargeback is suppose to do this. It can be setup in a "showback" model to be able to generate details to show usage numbers. Not sure if this gets exactly what you need done, but might be worth looking at.
If you just want organizational level stats you could pull that from the vCenter database within the VPXV_RESOURCE_POOL table. All you need to know is the resource pool name. I do this to create an external dashboard for each organizations overall resource view.
Power CLI 5.01 supports Get-CIVM and operations on Cloud objects.

You can use some more modules from this post as well. I use them all the time to transfer vApps to other organizations and update their network settings.
