That's just an animation right? Not an actual progress bar. It looks nice anyway.
There is a somewhat more dire problem when offering file uploads. Most browsers don't display a good upload bar on their own and the website just stalls while an upload is in progress.
After our mail exchange yesterday I've been playing around with HTTP chunked encoding. Here is a live chat that works without page flickering or polling. I've even tested it in Links2 ;-)
http://plutz.net/chunkchat.cgiTest it in different browser windows. There is a sourcecode link on the top right of the page.
The same technique might be usable for live progress bars. I came up with it after I remembered a conversation i've been having with a YaCy developer. The YaCy interface uses chunking to deliver the latest search results even seconds after a response page has been loaded. There are probably other implemenations around, this must have been working since the nineties.
I'm also working on some (better looking) CSS demos for different stuff.
