"Share on xxxx" button for Dolphin sites on others

What is the possibility of developing code to allow other sites to display a "Share on <insert your Dolphin site name>" button similar to "Share on Facebook" or "Share on Twitter", for example?

Upon clicking it would launch the users' Dolphin member page and auto-complete the 'Sites' form with the content that is being shared.

Any ideas? Many thanks for your thoughts.

I doubt you'll get a how-to through the forums. This seems like something that will take some work.

Sure, I just wanted to see if it's something anyone else had done and that I was staring at but didn't 'see'.

I'm only aware of integration with other sites for content sharing (e.g., share on Twitter, Facebook, Digg, etc.), but not the other way around. Someone may know, though.
