Yea I know, I am probably the last person on earth that is just getting around to using Paperclip. To be honest, most of my file upload code was written way before Paperclip or even AttachementFu was ever conceived. And frankly, I do not do much social app coding on the side - so the need never came up. But that changed recently and I wanted a really really good way of leveraging AWS::S3 storage with the best local app security while maintaining tight control over the files.
