Suggestion: if "idependent implementations" *actually means* "on different operating systems and/or hardware platforms," then that's what the checkpoint and the success criterion should say-- flat out, with no room for misunderstanding or misinterpretation.

Now what is happening is people are claiming accessibility based on technologies that can only be used on the windows/intel platform, and assistive technologies that do not run on window, can not, with all the will in the world, provide support. I see a big difference hear between developing based on a free download, or even a none non-free application, and developing for, say, only IBM with windows. (hay I use IBM and windows, but that is not the point) Part of the difference is that the user can get a new user agent a lot easer then he can sell his mac and buy an IBM. But the BIG difference is that developers of assistive technology for other platforms are barred from developing support. The do not have the API's. They can not do it. It seems to me that this allows potential monopolies, and such games to be played in the assistive technology/platform market. I think that it is the disabled who will pay the price. Any standard that are relied on for fulfillment of these guidelines must be open and usable on more then one, independently owned, platform.
