A little program called Dot.tunes. makes it possible to stream music from your iTunes library to your Wii. It creates a Flash-based player which you can then access via the Opera browser and play on your TV audio system compatible with Mac and Windows. However, unlike many other cool Wii applications, this one isn’t free. It does come with a 15-day trial before you need to register. Check Wii/iTunes Flash Player for detailed instructions on how to set-up the program.
