Wordpress MU 2.7. subscribe to RSS-feeds as mail

Looking for a WPMU-plugin that creates an extra tab in admin (for all users) called "Abonner" (means "subscribe"). Opens new page. On this page all feeds from system are listed - meaning blog-feeds, comment-feeds & category-feeds for each blog. List-items are links to the feed itself. There are checkboxes next to each line. After checking desired feeds that user wants to subscribe to, and "subscribe" button is clicked, feeds are sent as an e-mail to the users e-mail adress every time there is a new item in the feed. Will provide graphic mockup. ## Deliverables - has to be delivered as a functional WPMU plugin.
