it's sick mate .. WEB 2.0 and Ajax give your interface that bit extra. I am not sure if you will be able to see that behaviour but this is last functionality I achieved with Ajax
when you visit my page
Directory list at DirStast.com you will witness what I am talking bout. Just after I allow Directory listings to be updated in term of SE stats (happens rarely, cos I like to catche Dir StaTS) when you click on any directory link 'view details' you might see some magic ........
I needed that behaviour cos I was gathering few details about directories which was taking more than few seconds ...
