I've implemented this, with some frills.

Code is at and is probably  
rough around the edges. I'm not really a JavaScript hacker so it  
probably isn't terribly amazing quality, but it seems to work OK for  
me - I've been running it on several of my websites with a large  
range of user clue+access+OS+browser+ISP as visitors and I've had no  
complaints. The code is running on the page above, too.

The default timeout in the tarball is too high, 10000-20000 is  
probably adequate.

Please let me know if you use it, or if you do something similar or  
use it for inspiration or whatever.
In addition, I'm sure we'd all love to see any statistics you can share.
