Is ATI Stream Still Proprietary?

First I'd like to start by trying to explain a difference between Open Standard and Open Source for those of us who are getting confused. Yes, I may have been part of it myself in my last article. I kept on mentioning Open Source and Open Standard as if they were the same, even though while I was composing the Editorial I knew what I was trying to get at. Open Standard, which would be OpenCL, is something that is available for all to use, but even though it can be used by everyone, the actual source code (SDK) and it's tools are not open. They cannot not edited by the user nor can it be seen. Open Source, on the other hand, is something that can be used and edited by anyone and it is welcomed, since more sources can be added and, in theory, will create better development, thus increasing the amount of resources available to use.
