Open Stack

The JS may be served from a CDN. You can't assume a server-side proxy. Here's an example of a sever-less JS application that communicates directly to EC2: http://aws.amazon.com/developertools/1424 (there are versions for other services like SQS and SDB as well). Server-less JS applications are a fairly new breed of app that OpenStack should enable.
