Your best option is RTMPChannel/RTMPEndpoint and messaging in LCDS. The reason is RTMP uses a dedicated duplex socket connection between the client and the server, hence it's the most realtime option between Flex and LCDS. If you cannot use RTMP, your other options in LCDS are the following from better to worse:
1. HTTP-streaming channel on the client, NIO-HTTP streaming endpoint on the server. 2. HTTP-long-polling channel on the client, NIO-HTTP long-polling endpoint on the server. 3. HTTP-polling channel on the client, NIO-HTTP polling endpoint on the server. If you can't afford LCDS, then you can use BlazeDS which means you can still use the client side HTTP-streaming/long-polling/polling channels but on the server, you cannot use NIO-based endpoints, instead you need to use Servlet-based endpoints which means much less scalability per box.
