recent post widget for displaying top most site posts to all sub sites

i'm looking for a plugin that will take the TLD site blog posts and display them in a widget on all the sub sites.
i.e. http://www.mysite.com/blog/post-1 http://www.mysite.com/blog/post-2 http://www.mysite.com/blog/post-3

then on the sub site subsite.mysite.com display a list of linked posts back to the main bolg
--widget--
Recent News:

  • Link to post 1
  • Link to post 2
  • Link to post 3
    and so on

    this way i update/make a new blog post on http://www.mysite.com and all the sub sites will show the list of linked posts in a sidebar widget
