XMPP as the Future of Cloud Services?

From Matt Tucker’s “XMPP (a.k.a. Jabber) is the future for cloud services“:

There’s a new firestorm brewing in web services architectures. Cloud services are being talked up as a fundamental shift in web architecture that promises to move us from interconnected silos to a collaborative network of services whose sum is greater than its parts. The problem is that the protocols powering current cloud services; SOAP and a few other assorted HTTP-based protocols are all one way information exchanges. Therefore cloud services aren’t real-time, won’t scale, and often can’t clear the firewall. So, it’s time we blow up those barriers and come to Jesus about the protocol that will fuel the SaaS models of tomorrow–that solution is XMPP (also called Jabber) . Never heard of it? In just a couple of years Google, Apple, AOL, IBM, Livejournal and Jive have all jumped on board.

An interesting read on an increasingly attractive architecture.
