You know what? MSN web messenger is a cool piece of work. You don't have to install MSN messenger to use it almost like in real life. I love such amazing web work that looks like the real thing. Outlook web access 2003 does the same thing. Amazing GUI inside my browser. It scares me to think how many man-years were spent on making the GUI behave in such a way though. Really creepy.
Isn't the next logical step a Smart Client Messenger? or Outlook for that matter?
