ISO Social Media Comment Sharing Plugin

Hi everyone,

After doing a number of searches, I’m coming up empty looking for a plug-in that can do what one of our clients is asking.

They have a site where they are encouraging visitors to post comments. Once a comment is posted, they want that comment to have share buttons that will assist them with posting the contents of their comment into the social networking site of their choice.

So unlike any other social network sharing plug-in I’ve seen, they not only want to share the page, but they want to share specific content from that page.

I’m not entirely sure this is possible, but if it is, I am sure I haven’t found a ready-made solution yet. Assistance would be most appreciated. Thank you!
