Thanks James. I appreciate the info.

Right now, I prefer to upload to the local filesystem then process and store on S3 via DelayedJob. But I will give this a try.

Are there any plans for add-ons that allow EBS storage (or something along those lines)?

We aren't planning to provide any additional types of file storage, as we don't believe that the local file system should be used at all in a scalable app, as it creates state at the app server.

We do provide access to /tmp if you need scratch file space for processing (it is not persistent between requests). More info here:
