after I deploy one web-callback solution for lifepsychic.com,I deployed another flash p2p video chat service for another dating website,so people can talk with each other FREE,AUDIO,VIDEO,TEXT,and importantly it's peer2peer.it's based on adobe stratus solution,currently it's in beta ,we're waiting for its going public .it's really exciting technology. I can imagine web page communication goto higher level with its peer2peer support.
look at skype ,it overwhelm europe 90% voip traffic,but it still need install one software,but flash don't need install,and easy to integrate into web,so it should turn into millions of web sites voice/video-support with few investiment(at least few bandwidth )
