[quote="Drasa":24w7z09l]I wouldn't call it truly open e-mail-killer solution if it's still a service provided by one company. If there was open protocol so that anywho could create their own wave service which worked with other wave services, I would approve it totally.[/quote:24w7z09l]
You didn't watch the whole video, did you?
In fact, not only is the protocol open to any competing company, they demonstrate different wave clients running on different servers and communicating with each other in that video.
One of them is even a text-only client.
