Shephertz Technologies’ AppWARP also has SDK for Flash platform.
With AppWarp you can create real-time multiplayer games without writing single line of server code. You can simply make calls to our server through APIs and exchange messages with players in real-time. The Flash SDK should be 100% compatible with flashpunk framework, allowing developers to make realtime multiplayer games using flashpunk framework.
It features room/lobbies. Every room has some properties that can be set easily whenever developer want. You can even assign custom data to players and rooms.
Another feature is Match Making. We have great documentation too.
There are several features apart from above. Please check out our website http://www.shephertz.com/
Note: The reason to post it here is not for promotion. I am myself a developer working on this project and maintain the flash SDK. Since I am new to flash, I want suggestions and advices.
