SkypeWeb Allows Users to Track Presence Across Other Sites

Skype rolled out a new Web presence feature that allows people to see Skype users' online status and call or chat with them from any Web site as well as Skype people from each site with the click of a mouse.
The feature is being integrated into many web sites, including social networking sites (Bebo), online classifieds, online communities, etc.
