Thats a good suggestion that we can take a look at doing something like this within the business unit. Are you specifically talking about what integration we have with each connection broker providers?
Citrix can import VMs into XenDesktop that were created with RCU via a CSV file.
Quest vWorkspace can create the VMs by calling our ZAPI's
Leostream can automatically discover new VMs that are within vCenter that were created by RCU
Please give me some more details that you are looking for and we can try to provide some more info!
