Justin Everett-Church recently released some new details about the new RTMFP protocol that can be used with Flash Player 10. RTMFP stands for Real Time Media Flow Protocol and is going to be used to leverage the new peer to peer capabilities of Flash Player 10. The communication between peers is going to be managed by a future Adobe server technology (Flash Media Server 4.0???) which will keep a list of peers that can be connected to. If one peer want to connect to another, the server translates the peer IDs to a network addresses, and also assists in setting up the connection if one or both ends is behind a Network Address Translation (NAT) device. RTMFP is a UDP-based protocol and packets are sent directly from one Flash Player to another!

Some pretty exciting stuff to look forward to! I can think of a couple cool applications that could be built using this technology!
