Sure, MeetAndSpeak uses Comet long polling. There is always one XHR request
active so that the server is able to push new messages towards the client at
any time. Additionally all messages contain sequence and acknowledgement
numbers to guarantee that data is not lost without detection. The server
software itself is very low level and doesn't use any frameworks for
performance reasons. I'm planning to switch to WebSockets as soon as browser
support is adequate. There is way too much data and processing overhead in
HTTP when it is used to transmit big amount of small messages. Maybe W3C
WebSocket support could be even added to qx.io.remote.Rpc in the future.
