Preferred technology/framework to stream textual data to the browser?

we have some administrational webapp for a live chat system, and need to monitor the chat messages in realtime, amongst other events.

the events are stored in a mysql database.

what would be the best technology to handle a lot of frequent (near-realtime - every second) updates to the browser?

e.g. is there a way to use flex to stream textual data without LiveCycle Data Services (because it seems rather expensive and overpowered for this limited use case)  - what about BlazeDS?

(note: see my other question http://www.experts-exchange.com/Programming/Languages/Scripting/AJAX/Q_24327993.html for info on the current AJAX implementation and its problems)

limitations: must work on linux/apache/PHP/java (no microsoft)

You can use Coldfusion and BlazeDS or Java and BlazeDS to get real time chat applications.  BlazeDS is free and if you have java coders is a good option.  This can also be accomplished with Coldfusion alone if you have Coldfusion server.  Coldfusion and java will run fine on linux.

thx Jones911 - it seems BlazeDS does not support Publish and Subscribe messaging via RTMP, but only using 2 HTTP connections (one for each direction). do you see this as a major drawback?

in general - what other options are there, with emphasis on data binding?

what about JavaFX?

or even JMS with a Java Swing GUI, bundled as a java web start app?

JavaFX is a replacement for Flex as the UI.  I would not go with JavaFX from what I have seen its harder to code and slower.  Also JMS is part of Blaze see this link for some more information:  http://www.scribd.com/doc/11020541/Blazeds-Dev-Guide  

Basically we are using Coldfusion for all our backend Flex communication.
