Rafael, Thanks for the information. Is there any information in listTemplates which would indicate if a template is in multiple zones? e.g. is the `crossZones` parameter a reliable indicator - can we normally be guaranteed that there will be no duplicated IDs in templates where crossZones==false?
Currently jclouds will expect all templates where crossZones==false to have unique IDs. I am trying to determine if this is a valid assumption, or if jclouds needs a bug fix to be prepared for a duplicate ID at any time. Many thanks Richard.
