I have recently had the pleasure of testing my website on a Nintendo Wii and was pleasantly surprised to find that it viewed perfectly. This now brings my list of compatible browsers up to 16 (22 different versions), all of which are listed here.
The Wii browser is built upon the Opera web browser and supports AJAX & Flash (V7). Having done quite a bit of Flash development in my time, I have been playing with the idea of streaming music to the Wii. Currently I have built a simple Flash movie to stream radio from Pure FM, the radio station at my university. My first attempt (Which also incorporates their webcam) can be viewed here . The mp3 stream is 64Kbps and the webcam is set to update every 10 seconds.
