It may only be in prototype stage, but the idea of Nokia's EasyMeet is something that is perfect for the wireless mobile worker of the future.
Wireless Moves has the details, to the concept that sounds much like Pronto from iotum, a proof of concept play that Alec Saunders introduced at DEMO a few years back that led to iotum winning a DEMO God Award.
If you watch the Easymeet Demo video, you'll see lot of similarity between the EasyMeet concept and iotum's Calliflower service which is already available today.
You can also try the beta version of easymeet online as well. The big difference is Easymeet is combining the Nokia devices and services platform, while also making the invitation media rich, while Calliflower is making the experience richer during and after the call.
