I agree and I imagine AWS, will meet this expectation, eventually. Keep in mind that the Cloud idea is still relatively new. Just look at the history of Amazon's Serivces[1] and you can see that this is the direction that they are going. I think this marks a turning point for EBS. I said this same thing on reddit and was mocked but can you really imagine Amazon letting this happen again?
