We announced earlier this year that we’d open up the specifications for Real-Time Messaging Protocol (RTMP is the protocol used by Flash Media Server and LiveCycle Data Services). We did it today, and you can read the details here.
Basically you can download the specifications and start implementing your own servers that make use of this highly efficient protocol for sending data between Adobe Flash Player or Adobe AIR apps and various servers.
It is worth noting that we didn’t open up anything related to RTMPe – Adobe’s implementation to secure the content. While you as a developer don’t have access to our implementation, you are free to implement your own secure implementation on top of RTMP.
