WordPress MU

hey people can anyone please help me to find a single plugin where
featurespost,recent posts and recent comment can be seen in a single Ajax like script for wordpress mu.
please help me to find this i am really desperate of searching..

hey, what's 'featurespost', sounds like an interesting idea (if it exists?)... i'm excited- is there a way in WPMU to 'promote' an interesting post from any blog to the main page on, say, push of an admin's button? 'featured post' that'd be a cool plugin!

----

if you could find a good RSS plugin (there must be one) to create a feed for all your blog's comments / posts / whatever surely there's ANOTHER ajax type plugin (like: http://wordpress.org/extend/plugins/post-ticker/ ) that will allow this data to be displayed. just an idea!

sorry, i'm new here!! the featured post idea does exist: http://wpmututorials.com/plugins/featured-posts-plugin-and-widget/

Thes all exist, but not all in one plugin.

http://wordpress.org/extend/plugins/wordpress-mu-sitewide-tags/

Do that, and the tags blog will have one feed address for all new posts.
