Um... it might even be possible.
The only reservation that I have about this is that it requires 
Javascript. Many people have JS switched off due to security concerns. 
(Even after years of availability, there's still an advisory every month 
or so, with a line that says something like "Workaround: switch off JS 
until a bug fix was installed".)

That said, I'm not 100% sure about the details of ajax. I'm currently in 
the wait-and-see phase. Browsers seem to scramble for "Ajax support", so 
it may be the Next Hot Thing Since Sliced Bread, but if it starts to 
show up in advisories like JS, it's worthless outside trusted circles 
(say, a corporate intranet - and even there I'd take care, some 
corporations are snake pits and not above playing dirty in the intranet).
