Hi Nick, I did some work with CORS a few months back [1].
At the time I couldn't get any browser to work properly with CORS so I just parked the code. The problem was lack of support for the Access-Control-Expose-Headers header. According to the Chrome bug report [2] this issue may well be fixed now so I need to retest.
