Comet (long polling) for all browsers using ScriptCommunicator. More Comet from the Plurk team: 80 lines of dependency free JavaScript implementing long polling using script tags (hence working cross-domain) across IE6+, Firefox, WebKit and Opera. The clever bit is the code to detect loading errors. It doesn’t try to fix the infinite loading indicator problem—is that still a cromulent usability concern?

$.comet (via) The first Comet (with Bayeux) plugin I’ve seen for jQuery—currently only handles long-polling over XMLHttpRequest, but still a promising start.
