Would an S3 cache module for IIS7 be useful?

Question

Would it be useful to have a module for IIS7 that automatically caches images and other static content to S3 and replaces references to them in web pages?

What would be the pros and cons, and things to watch out for in making this?

Answer 1

If you are going that far, why not just host IIS in AWS?

Answer 2

It would need to work with Amazon CloudFront (use S3 as origin and is faster than S3).

I'm not 100% sure it's IIS's job, but it looks like.
