Quite intrigued by the Kickstarter offering from Imageflow, a proposed web server utility that handles image resizing and security. On the top level surface, it's very similar in functionality to what ImageMagick and imgix are already doing but with a more focused effort on keeping information secure and serving optimized resources for mobile devices. On the whole, it's a nerdy offering but the pitch is quite sound if you're the type of person concerned with serving front-end assets and keeping your server secure.
