My understanding is that you would not have to pay for end-user access
to S3 content if you're using Cloudfront. You'd pay for end-user
access to that content via Cloudfront, and you'd have to pay the
normal S3 upload and storage fees for your own access to your bucket.

That said, I would not bet the farm on my understanding here, as I
haven't really looked that closely at Cloudfront yet.

Well, I don't know if it solves that problem or not, but because this
service is aimed specifically at HTTP usage for end-users of a web
site, I wouldn't be too surprised if they had. S3 really is just
general-purpose storage, and just because you get to it via HTTP
doesn't mean they've spent a lot of time figuring out how to make it
work well for HTTP end-user access.
