[ sorry, mis-send. ]

Here's a post from Vlad, who works on WebGL on the subject of native arrays:

Note that we're working on adding interfaces to expose this from XHR, 
Vlad has expressed interest in doing the same to the WebSocket DOM 
interfaces and we're working on one from the File API as well. 
Basically anywhere where the browser is expected to handle a big pile of 
binary data, we should probably be exposing interfaces to expose them as 
native arrays.
