Thanks for posting this. I was looking at adding uploads just this morning, so this is very timely. It looks like if you combine the direct upload to S3 as outlined in this article with bitline (http://www.blitline.com/ http://www.blitline.com/), you get some pretty cool abilities. I especially like that bitline supports batch operation (for example create five sizes of my image) in one call.
