Possible Spectator Mode for Xbox2
BlueMoon writes "Spong.com posted an article about a new Microsoft job offering. The job details not only confirm the internal codename of the next generation Xbox console is Xenon, but it also reveals more information about Live features. It looks like many games will have a 'Xbox TV' feature allowing some sort of spectator mode with tickers at the bottom of the screen featuring recent high scores and game highlights, a tournament system, and tradable trophies."
Half Life (and its mods) has had this for years, HLTV. You can just open up the spectate tab in Steam under servers and there they are.
