ICD and OpenCL on Windows CPU + GPU. How?

I browsed through the posts looking for answers to my questions and found some. I still have a few questions:

  1. Does Intel provide OpenCL dlls for Windows? I know that AMD does that and apparently their drivers works on Intel CPU but I could not find an Intel driver yet.

  2. Is the ICD extension mechanism working on Windows or is it too early yet? Can I actually use multiple OpenCL dlls on the same computer with ICD right now?

  3. What would be a good model for getting the OpenGL dlls on the client’s computer for a Web browser plugin that uses OpenCL ?

  4. Can we expect a client computer to have the OpenCL dlls installed when they first install or when they upgrade their graphics card drivers? And what about the CPU OpenCL dlls?

Those are my questions for now. Any help is appreciated.
