hello, i run a social networking site written in asp.net and would like to open it to developers using the OpenSocial APIs. I have read information on opensocial.org as well as google's opensocial page and have a basic idea what it takes but still there is a lot of info missing to even get started.

I know i gotta provide RESTful API as well as JavaScript API, authenticating using OAuth methods. Does my container has to provide all 3: JSON, XML, and AtomPub representations of data?

I found Shindig but it runs under Apache, i need something for IIS. Are there any libraries that i could use as a base for my APIs to save time? Is it even recommended to write the entire container from scratch?

thanks
