I've had enough of this real-time web silliness. Threading and networking on the client side is exactly what it seems. "Real time" is something entirely different than a client-server metaphor, which is all this browser thing has ever been. The difference? Real time applications run discrete logic on bare metal and have sub-millisecond response time. Web applications that use multiple data sources with short update periodicity is what it says on the tin. As many HN links hint, REST = CRUD, AJAX = TCP/IP and what was old is new again. However, while the future may look like a cheaper IBM-style mainframe-to-the-world thing, it just looks like web services via vendor lock-in to me. Like a low-rent version of SUN's old slogan.
