In a similar vein, I'd like to see a "ticker"-type node which returns ONLY nodelets — either the ones set up in your user configuration by default, or an explicitly requested list. E.g.

/?node=nodelets;nodelets=personal,xp,ticktock,chatterbox
[download]

If there were such a thing, I'd put it in a firefox sidebar. And then I'd turn off all the nodelets in my regular page view.
