Oregano Server is a Multiuser Server for Flash Clients. It is written in Java. It is useful for client-server applications that require low latency such as real-time chat systems, shared whiteboard applications or multiuser games that would be difficult to develop with traditional HTTP-based solutions
It is free and released as Open Source under the GNU Lesser General Public License (LGPL).
Oregano is on hiatus. It is unlikely that there will be any further releases.
The Client API is available
for AS1 and AS2. If you are going to develop in AS3 and/or need features like Video/Audio Streaming and Broadcasting you
may want to look at Red5.
Download
You can still download the final release from 2004 here. The download contains all binaries needed to run the Oregano Server, the AS1 Client API, the admin tool, an example application and java source files. The official release contains only the Client API for AS1. You can download the Oregano AS 2 Client (contributed by Eric Priou) here.
