Yiorgis Gozadinos from Jarn recently released some amazing new work last week, a suite of packages called jarn.xmpp.* that enable powerful real-time interactivity in Plone, including:
- Real-time simultaneous document editing (that’s right, just like Google Docs!)
- Instant messaging/status updates between Plone users (think Twitter or Yammer)
Yiorgis has a great little video that shows this in action. Pretty magical.
