I like this idea, my gut tells me there is something in that arena to be solved with some simple like this (maybe even a universal JSONP callback method definition for an endpoint or something for services that you can call out to for things like this?) I wonder if the actual usability of this is what stymies it... for example, say SmugMug exposes their image filtering API that they use to sharpen and enhance uploaded images and Flickr exposes their geocoding API to allow you to pass in GPS coords and they write them into the JPG meta for you... what is the motivation for these services to expose these services to 3rd party (potentially competing) web applications to make use of them? I am assuming you have access to these services because you are already customers of those companies, wouldn't they want to keep you in their garden? If you put this in a pot and boil the water off of it, wouldn't this idea more or less come down to the problem web services are meant to solve and in that way end up with a similar looking ecosystem? Not critical of the intents idea, just trying to think of where this goes once it exists to get a better idea of how it should be designed/pitched/used/thought of. Thoughts?
