One thing that has not been really clear is what is SAP position for non-SAP customers that require an On-Premise for eProcurement? Is Ariba On-Premise an option?
This is evolving into a significant issue for some non-US based companies and government organizations that have taken a stance against cloud solutions hosted in the US due to privacy issues related to the Patriot Act/NSA. I understand that if those organizations have SAP, then they are offered SRM, but some of them do not have SAP as their ERP.
