Tony Hirst links to what is self-described as 'the most accessible media player on the web' developed by the British government's Office of Disability Issues (ODI). I tried it out and it certainly seems to cover the bases - described video, captions, screen-reader support, big buttons (so nice for someone like me), toned interface, and more. What I didn't see, unfortunately, was a way for me to use the player to distribute my own media. So the 'most accessible media player in the world' plays exactly six videos. What's the use of 'the most accessible media player on the internet' if people can't use it? Here's on the player, and there's the player itself.
