示例1: modeStreamDataToSL
// This experimental mode sends chat messages into SL on a back channel for LSL scripts
// to intercept with a listen() event. This is experimental and not sustainable for
// a production feature ... many avatars using this would flood the chat system and
// hurt server performance. Depending on how useful this proves to be, a better
// mechanism should be designed to stream data from the viewer into SL scripts.
