PlayOn's media serving software is now available (in beta form) on the Nintendo Wii.
I use PlayOn on both the 360 and the PlayStation 3, and it is awesome. It allows you to make the future happen on your PS3 by letting you stream Netflix movies to your TV, as well as feeding Amazon VOD, Hulu and other internet video to both game systems. The Wii version will bring the same functionality to Nintendo's device, potentially making the Wii a viable, cheap media extender with an awesome point-and-click remote control. If it works, I could easily see the Wii as the center of an internet media enabled entertainment system.
You can download the new version of PlayOn to your Windows computer (sorry, Mac users) right now and give it a shot: Although eh software costs 40 bucks, PlayOn offers a free trial. If it works as flawlessly as the 360 and PS3 versions have worked for me, that's a very small price to pay for a great program... of course, my PS3 and 360 are both wired to my network. I'm not sure how smooth the Wii's wireless functionality will be when streaming video.
