More Than Just Jabber. jabber + groove:
“Whiteboarding document sharing inside of a Web browser—collaborative browsing, they call it. A lot of applications already do this. But what we’re building is one generic architecture that can really handle the back end for all sorts of those applications. Say you’re in Palm Pilot and you want to sync your address book. If you had your address book defined in XML—working with SyncML synching it up to your server—these applications might be using Jabber to send or receive these things on the fly. When you update your address book in one application, it’s automatically pushed out to the server The server announces the change to all the other applications listening to that XML, and they receive those updates. ”
