SWFUpload has not been under active development for several years.

Here are my desired features, though none of them are nessesary

kgu87 is correct, this article pretty much explains the entire process to upload files directly to S3 without passing them trough your own server.

You can also check out the AWS docs related to this on:

http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingHTTPPOST.html

http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPOST.html

If you're looking for an upload tool that supports HTML5 uploads directly to S3, check out Plupload

They have a great article that explains how to set it up:

https://github.com/moxiecode/plupload/wiki/Upload-to-Amazon-S3

The documentation describes a PHP service that's used to generate a policy and signature (both are required for S3 to accept your download) but you can use any language to generate those. Also, in certain use cases, you can just generate a one-time policy with a very high expiration time and hard code it into your upload form.
