Yeah, I guess the question is whether we should put the functionality into ArrayBuffer, or into a wrapper class which would part of the Web Worker spec. The latter might make it easier to add other resources (like image and canvas) at some point. But I agree, it should be implemented before finalizing anything. Did I hear you volunteer to add a strawman proposal to the Typed Array spec? :-) ----- ~Chris cmarrin@apple.com
