Microsoft is at it again. Its Microsoft .Net passport efforts tanked, so the Redmond giant is now working to create another type of a universal I.D.: a gamer's passport.

Last weekend, I went to the GarageGames indie game developer conference in Eugene, Ore., where I talked with Greg Canessa, group manager for Xbox Live Arcade who demoed the new Xbox 360.

And Canessa says that Microsoft's Xbox Live team has come up with a nifty new idea, of a lifetime gamer I.D. In some ways, it makes a lot of sense: Say, you buy the Hexic puzzle game from Microsoft and download it via the Web onto your console. Then, your little brother spills milk all over your console and it breaks. You will need to buy the game all over again, right? Wrong!

With a lifetime gamer I.D. assigned in your name, Microsoft will know that you've already purchased the game and will provide you with a copy for free. What's more, the I.D. will track your game scores and your rep with the Xbox Live community throughout your life. It's a sort of a gamer's passport.

What I'd love to know is, do you like this idea? Or do you worry about invasion of privacy, which was a concern when Microsoft spawned Microsoft .Net passport, which didn't end up going anywhere. Would you want Microsoft to keep track of your gaming experience?
