The Khronos Group has just ratified the standard for WebCL 1.0. The API  is expected to provide a massive performance boost to web applications  which are dominated by expensive functions which can be offloaded to  parallel processors, such as GPUs and multi-core CPUs. Its definition  also allows WebCL to communicate and share buffers between it and WebGL  with an extension.

Frequent readers of the site might remember that I have a particular  interest in WebCL. Based on OpenCL, it allows web apps to obtain a list  of every available compute device and target it for workloads. I have  personally executed tasks on an 
NVIDIA GeForce 670 discrete GPU and other jobs on my 
Intel  HD 4000 iGPU, at the same time, using the WebCL prototype from Tomi  Aarnio of Nokia Research. The same is true for users with multiple  discrete GPUs installed in their system (even if they are not compatible  with Crossfire, SLi, or are from different vendors altogether). This  could be very useful for physics, AI, lighting, and other game  middleware packages.
Still, browser adoption might be rocky for quite some time. Google,  Mozilla, and Opera Software were each involved in the working draft.  This leaves both Apple and 
Microsoft  notably absent. Even then, I am not sure how much interest exists  within Google, Mozilla, and Opera to take it from a specification to a  working feature in their browsers. Some individuals have expressed more  faith in WebGL compute shaders than WebCL.
Of course, that can change with just a single "killer app", library, or middleware.
I do expect some resistance from the platform holders, however. Even  Google has been pushing back on OpenCL support in Android, in favor of  their "Renderscript" abstraction. The performance of a graphics  processor is also significant leverage for a native app. There is  little, otherwise, that cannot be accomplished with Web standards except  a web browser itself (and there is even some non-serious projects for  that). If Microsoft can support WebGL, however, there is always hope.
