Is there plugin to drag/drop directly from RSS to posting

Is there a plug-in or hack that allows a drag and drop of feed information into a post being created by user?

I’d like for editor/users to be able to respond to newsfeed items by dragging and dropping an RSS feed item into the respondents posting. The user could crop what ever wasn’t needed from the feed during post creation.

This way the user could provide information directly from the feed without retyping or rewording it, thereby creating a response posting more quickly and better documented.
