Skype about to reinvent

Thanks to Pil for the news :)
Skype has been working on a portable phone prototype, working on a WiFi network to get access to Internet.
This "mobile" phone wouldn't use any operator's network, but Internet and Wifi, currently spreading so fast everywhere.
Simply enter your Skype account parameters on the phone, and all your contacts are available.
Skype having planned to implement its communication protocol with video, I let you imagine the further possible developments to such a prototype.
Soon phoning for free? :)
