Playing your DRM'd iTunes music on your Wii is the headline of the day. Through the use of a program called
dot.Tunes you can access all of your iTunes music and stream it from the Wii. The way this works is that dot.Tunes provides a flash based interface to your iTunes library that you can access from anywhere on the web. The Wii has the Opera browser, surf to your computer from your Wii and away you go. Of course this functionality isn't limited to the Wii, as the PSP has a browser as well, meaning it can stream your music from anywhere there is wireless.
