The rendering itself shouldn't be much of a problem. Since http://www.zark.com/ which already worked on Netscape 2 (yes, the old stuff, not Firefox or Mozilla) I think you can do more or less everything, even something like the stack-application he linked in his OP. The biggest problem I see with the fact, that incoming data leads to an immediate rendering of a part of the page. So if two diggs are happening this lead to two "drops" tearing down at the same time, so you need something "Comet"-like that allows a push from the server to the client and a busy-wait-loop that renders the different drops step by step, changing CSS-properties for the fade-in/fade-out effect of the links that are shown below (the latter is already available with third-party). The busy-wait solution is what makes me suspicious that GWT is the right choice for that. With Flash or Java or whatever the implementation is easy. As soon a new entry has been received from the server a Thread is fired up that handles the fade-in/-out and tearing down of the drop. As soon as the rendering of that drop is finished, the Thread dies. In a singlethreaded environment you have to keep an array of currently to be rendered elements with their current rendering states (e.g. element 1 has teared down 25% of the distance, element 2 30% etc.). The busy waiting loop checks that array for elements to be rendered and renders the next nessecary step for each element. I'm quite sure that you don't need to worry about you coffee getting cold if you place your cup next to the heat-sink of your computer ;-) > Flash (which they used) or an applet (java or > whatever Microsoft is calling an activex control these days...) would > make your life easier.
