Blobs now allow further binary data operations by exposing an ArrayBuffer property that represents the Blob.  ArrayBuffers, and affiliated "Typed Array" views of data, are specified in a working draft as a part of the WebGL work [1].  This work has been proposed to ECMA's TC-39 WG as well.  We intend to implement some of this in the Firefox 4 timeframe, and have reason to believe other browsers will as well.  I have thus cited the work as a normative reference [1].  Eventually, we ought to consider further read operations given ArrayBuffers, but for now, I believe exposing Blobs in this way is sufficient.

File inherits Blob, so everything that is available on Blob is
available on File. This is similar to how HTMLElement inherits
Element. getAttribute is available on HTMLElement, despite being
defined on Element.
