We don't currently have cross-domain or JSONP support for the API. Could you tell us more about what you are building?
If I pull it off it may be for sale. LOL kidding. I am trying to get interface stats from swql query, which I basically can do. The goal is to build a interface traffic view that does not require me to manually create each graph. I want to have various pages that may graph all interfaces that match a certain custom property. If I add a property to the interface it shows up on the page dynamically. Also I could have a property for page order and then add it to sort the graphs. Etc etc
