So NetApp just announced this: http://www.netapp.com/us/company/news/news-rel-20121128-693554.html

I am not familiar with Amazon's offerings, but it sounds like you can stick a filer in certain datacenters have your clients continue to access a primary filer via nfs or cifs and then snapmirror that filer to a secondary filer that magically writes it to the cloud?

The details are a bit light from what I have been abe to find online, so I am curious if anyone has any additional information.

Thanks
