Social Networking Aggregation Services

Hello.

I'm wondering if anyone can recommend a social networking aggregation service that works well with Unity.

What I mean by a aggregation service is something that sends links, messages, and images to multiple social networks (such as Facebook, Twitter, Pinterest etc), using a single API. Examples of aggregation services include AddThis or OneAll, but those don't work too well with Unity. Something with a simple HTTP or Javascript would seem the best for me because those are things Unity (Webplayer and Flash) can talk to with relative ease.

I'm not interested in plugins that handle one or two specific networks, or that specialize on one or two platforms (such as the Prime31 Social Networking plugin). I'd prefer something flexible that you can talk with over the internet, whether you're using webplayer, and iOS build, or a standalone. The service doesn't need to be Unity specific but it shouldn't rely on me placing their specific buttons on the website next to my Unity view. I need something I can talk to directly from Unity or via direct Javascript commands.

Thanks in advance for any responses.
