The Plazer is a little software that can locate you automatically with your PC or Laptop. It integrates into iChat to let other people know where you are. The Software acts as the local part of Plazes (http://www.plazes.com), a location based service, that let's you discover nearby locations or people based on where you are and recommends things you should check out or people you should meet based on your past whereabouts. Plazes also offers a cool badge you can integrate in your personal profile page (e.g. on Myspace or Tagworld) to publish you current whereabout.
