Tafiti, the experimental search engine based on Silverlight, was updated recently and now offers more Windows Live Services integration. The update includes the use of presence and P2P messenger APIs that allow you to now share your search favorites with your IM buddies. To see this new feature in action, you'll need to sign into Tafiti with your Windows Live ID. If you're already signed into Messenger on your PC, you'll be signed out there and then signed into Messenger on tafiti.mslivelabs.com. Check it out for yourself - the new site is available here: http://tafiti.mslivelabs.com/Default.aspx.
