DNN Social News Module, users can vote on news article quality, votes stay with news article poster

I'm looking for a peer-submitted news module, or a hack of modules, where registered users can submit, comment on, and vote up other registered users' news links.

This is similar to Y Combinator's HackerNews site http://news.ycombinator.com/ , or the www.slashdot.org news site. Pics attached might help describe goals


Here's the walk through:

• UserA submits news source link, article title, category, meta and some opinion text to NewsArticle1
• NewsArticle1 is published to the site, with a list of other articles submitted by registered users. World can see it
• (NewsArticle1 is just a target_black from my site to actual news source)
• UserB, UserC, UserD etc can comment on NewsArticle1 on my site, view others' comments, vote to increase UserA's points by one, and add meta tags to better categorize news
• UserZ (on my site) posts a link to NewsArticle1, cannot create new instance of NewsArticle1. Is instead redirected to UserA's post on NewsArticle1 (and can see UserB, UserC, etc comments)
• Must be registered user to Vote up an article, must be registered user to add new article 

 
I've played around with some modules, but am not sure the right hack for this. Any thoughts would be appreciated.


Thanks
