Adding UDP-based RTMFP protocol and Speex audio codec in Flash Player 10 were right moves from Adobe and it allowed us to notice that FP was about to become a good VoIP client. But even with RTMFP capabilities Flash Player couldn’t connect two clients using P2P behind the specific NATs/firewalls, so fallback to server’s relay was required in such cases. With new features of Flash Player 10.1 (RTMFP groups) everything changes, now peers from RTMFP group will help you to do P2P media transfer if direct P2P connection between some 2 peers from the group isn’t possible. If you think a little it will become obvious that FP can be used to create P2P-networks like Skype’s one, root servers will only deal with signaling and will help clients to join groups with peers that can help in media delivery. It can be used in many services. Now we need Acoustic Echo Cancellation support and more advanced video codec for encoding video from webcam (h264, for example) to create web-based Skype.
