Javascript Unique Browser Fingerprint (Like Panopticlick) *RUSH*

I want a javascript script that will return a unique fingerprint of the browser. It must use all of the features detected from: <[login to view URL]> The script should detect all of these features (as on the above link), append them all together and calculate the SHA-1 hash of this value. It should be very easy for me to use, just include the javascript and then something like: var fprint = GetFPrint(false); The result will be only the final SHA-1 hash. This is a rush job! Please complete (and test) within 24 hours.
