I have just found out this website http://webkit.org/blog/603/webgl-now-av ... nightlies/ which says,
"WebGL is a new standard being worked on in the Khronos consortium. The work done in Khronos is only available to its members, so I canít show you the spec just yet. But it will become public within the next few months after a review by Khronos members.". It was posted on October 19th, 2009.

Where can I find the following info?

What are the key deliverables? Specification, utilities, tools, (conformance) test suites, etc. Many OpenGL apps use the glu.h and Windowing specific extensions (WGL, GLX, etc).
When are they going to be available for public (beta, final release, etc)? I only found http://www.nihilogic.dk/labs/webgl_chea ... _Sheet.htm

Those info would be useful so we could plan accordingly.
Thanks in advance for your help.
