I really apologize for a very cursory read on my part, but I'm guessing it is in the same manner that CORS uploads to S3 is handled: http://aws.amazon.com/articles/1434/

There seems to be more details here: http://aws.typepad.com/aws/2013/05/aws-iam-now-supports-amaz...

Again, I didn't have time to read all of this and see if it is done in the same manner as has been possible with S3/CORS for the last year or so.

If your application is only using S3 to upload objects, the full SDK would probably be overkill. Using pre-signed forms is sufficient there. However, if you want to use other services like DynamoDB, SQS, or SNS, pre-signed URLs will not work. Also note that in order to generate a pre-signed URL you still need a backend service running to sign those URLs, something you can avoid with the client-side SDK.

Ah ok yeah that makes sense. Pre-generate a signed token and post it along with the form. I guess in that case you wouldn't even need the jS-SDK since you can just do a normal POST/PUT to the s3 bucket with those credentials. I guess I got excited only to realize nothing would change ;)

Thanks for your help!
